This is mostly related to canon, but also a bit to HPMoR.
I’ve always wondered why the killing curse counts as “unblockable”. In “Order of the Phoenix”, Dumbledore blocks it by moving a statue in its path. Seems to work nicely. There is other evidence that solids stop the killing curse—if it went through it, you could accidentally kill somebody behind a wall when missing your target. Prof. Moody would surely have mentioned that danger when talking about the killing curse, if that was the case. So you could carry around a steel plate strong enough to block the curse, and quickly move it into its path. Not easy, but possible.
There are also several instances where simple spells conjure animals (I remember bats and small birds). I wonder if you could simply conjure an animal into the way of the killing curse. It might need to have a minimal size to work, but a powerful wizards should be able to do that.
I also wonder if there are ways to combine charms: one detection charm that triggers another one. For example one that detects killing curses, and enables apparation or a portkey.
So, one proven way to block a killing curse, one conjectural, and another conjectural way to escape it. I can’t believe the wizards still call it “unblockable” :-)
I’m pretty sure that ‘unblockable’ is meant to mean it was the only magic known to have no counter-effect, or counter-spell. Now Harry has discovered the true Patronus charm is the counter spell to Avada Kedavra. It makes sense when you think about it, which I’m sure is why Eliezer included it in the first place. The Dementors are voids of nothingness, into such nothingness tumble all living things once their life is extinguished (according to present evidence, anyway); in other words, the Dementors are parts of Death, but are not Death Incarnate (which can be summoned according to a Dark Ritual Quirrell read tell of as a spritely young lad). Thus, if the Patronus charm has the ability to repel a piece of Death, then in accordance with magic’s apparent system of dualities, the Patronus charm must represent the opposite of Death: Life.
All but Harry cast their Patronus using memories, figments of the mind based upon reality; because they only conjure a thought reminiscent of all life can be, they can only manifest a fragment of life force to shield themselves from Death—an imperfect shield, permeable to Death. Harry recognizes the two poles of reality: Death, or absence—and Life, or presence. Harry brings to mind all that reality really is to us, namely all that a life can ever possibly experience, and pushes that in the face of the part of Death that is Dementors.* Harry has this ability because he strives to and greatly succeeds in deceiving himself of nothing (he’s not perfect—yet); through rationality he is able to have an accurate enough map of the territory that his conjured thought actually is a picture of all life can be, and so he can manifest the entirety of his Homo sapiens sapiens being. His Patronus not only represents but is pure life force, so it can overwhelm and obliterate imperfect representations of Death id est Dementors.
Likewise, as both Dementors and animal Patronuses are imperfect representations of their respective pole, their effects more or less cancel; an animal Patronuses’ ability to repel a Dementor is in apparent proportion to its representative accuracy. Harry’s true Patronus is the the form of Life itself, and so he can destroy Dementors and cancel Death; Dumbledore accepts most of the Life dimension of reality, and nearly all of the Death dimension of reality, and so his representation of Life, his Patronus, is the strongest and brightest yet mentioned.
Now comes the tricky part of this hypothesis. The Killing Curse is equal to death in that if struck by it, assuming no inherent rule of magic regarding altruistic protective love interferes, you will die. The true Patronus has demonstrated the ability to overpower and destroy imperfect representations of Death, as it is the duality opposing Death in true form. However, the Killing Curse and the true Patronus cancel, so it must then follow that the Killing Curse is Death in true form, but not Death Incarnate.
However, this theory is completely blown away if the true Patronus doesn’t cancel the Killing Curse at all, that Harry blocked Quirrell’s Avada Kedavra merely by effecting an interaction of their magic. Whether the true Patronus can truly block the Killing Curse remains to be seen.
*From what I’ve gleaned from the text, I do not think Harry’s statement, “I think of the absolute rejection of Death as the natural order [paraphrased],” accurately reflects his thought processes preceding the casting of the true Patronus; to reject Death is to acknowledge it, and I don’t think Harry acknowledges Death at all when casting the charm. Furthermore, I do not even think it possible to cast the true Patronus when thinking of Death at all. When casting the charm, Harry calls to mind all that Death isn’t, and all that life is; he thinks purely of life, with not even a single shard of a thought of Death in mind.
As an aside, I find it particularly clever how in contrasting everyone else in the wizarding world, or agents of general humanity, with Harry, an agent of rationality, Eliezer characterizes animal Patronuses as akin to the self-deceptions and biases of most of humanity, and the true Patronus as akin to the power earned through the diligent application of rationalist techniques to everyday life, through elucidating the difference between animals’\ capacity for understanding and human capacity for understanding. \Excludes humans as a subset; the sentence becomes awkward otherwise.
My assumption was always just that the “summon death” bit referred to creating a Dementor, and that they are much more directly about death than simple nothingness. This isn’t necessarily implied by the text, but it seems the more likely explanation.
And yes, you can definitely argue with the author about their own characters, to a certain extent. (I.e., “He’d never do X, Y is way more like him!” okay, “Harry is actually a 57-year-old woman!” not okay). You’re well within the lines here.
… the most terrible ritual known to me demands only a rope which has hanged a man and a sword which has slain a woman; and that for a ritual which promised to summon Death itself—though what is truly meant by that I do not know and do not care to discover, since it was also said that the counterspell to dismiss Death had been lost.
Chapter seventy-nine, HP:MoR
I can see your interpretation, but Quirrel’s commentary does not lend it credence. He does fear Dementors, or rather their effect upon him, but—no, your interpretation holds; regardless of how high a probability there may be of the spell merely summoning a Dementor, the inability to dismiss what’s summoned leaves too high a risk of freeing something worse.
Though I would think Quirrel would clearly express those concerns over opting to speak warily and vaguely of the ritual—and I think it out of character for him to not have thoroughly contemplated it.
That’s ridiculous. It’s ridiculous that the curse would be considered unblockable under those circumstances and ridiculous that I didn’t think of that already.
And yet… it seems you’re right. In fact, now I think it would make sense for wizards to use shields in duels.
harry carries around a small boulder as ring. the transfiguration could be finite incantem’d before battle. although quirrel did say that most magic battles are actually ambushes.
You need to remember how wizards think. If the killing curse can’t be blocked by spells, then it simply can’t be blocked. They mean that if you use it in a duel, it doesn’t matter what sort of shield spell your opponent has up, it won’t work, and so the spell isn’t very sporting and therefore is unforgivable.

Does Quirrell know that Dementors are death? I think Quirrell’s interpretation is based on a lack of data, not on a difference of opinion.
Indeed, I see your point. The theory still holds should the ritual summon one Dementor or many, and I’ve benefited from considering it; thank you.
Am I arguing with the Eliezer about his own character here? If so, is that allowed?
That’s ridiculous. It’s ridiculous that the curse would be considered unblockable under those circumstances and ridiculous that I didn’t think of that already.
And yet… it seems you’re right. In fact, now I think it would make sense for wizards to use shields in duels.
Assuming shields light enough to be practically carried could be thick enough to block it.
And someone could just cast evanesco on the shield, now that I think about it.

Harry’s patronus also blocks a killing curse, in Azkaban (in HPMoR)
