I get that this is humorous, but it seems like it illustrates the point of why this strategy is useful in the first place: memory is not human life, does not feel pain, and can even be resurrected from swap (which might still take some extra time but still is way less of an issue than the corresponding problem for humans)? If the strongest objection to the system is that it can't be ethically generalized to apply to managing people instead of memory, I think I'm happy with it. I don't care about whether it's inelegant if it works well enough for me in practice when the "victims" are arbitrary values in memory.
