I lied. I had a couple of pending pulls, so I couldn't go lie down
anyway, so I tried to take another look.

It *might* be as simple as this incremetal thing on top, but then I
think that code will no longer trigger on the stack movement case at
all, since there we don't work with the whole vma.

So if we want that to work, we'd have to fix that up too.

And this might be broken anyway. My track record isn't looking so hot right now.
