Yes. That was why I'm nervous about it. I'll put it into 2.1.77 now that I did it anyway, to get more people to test it out and comment on it, but we'll have to keep this in mind.

No, no reverse page tables. The data structures to keep them up-to-date worries me (it would essentially involve doubling all the page tables). It comes up every once in a while, but I'd really like to avoid it if at all possible.
