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.
