There was a lot of words; but I'm still not sure what it actually does.

I've read some of the code that followed; is it simply sampling the
page-table access bit? It did some really weird things though, like that
whole 3 regions thing.

Also, you wrote you wanted feedback from perf people; but it doesn't use
perf, what are you asking?

Perf can do address based sampling of memops, I suspect you can create
something using that.
