OK.
Don't get me wrong - I do think this is neat code and is a good way of addressing the problem. (I'm surprised that the mmap protopatch didn't touch rmap.c).
But I don't think it's a slam dunk and I would like you to appreciate the constraints which I believe we operate under. And I don't think we've adequately considered alternative solutions to the immediate performance problems.
