SubjectRe: [PATCHv2] Add per-process flag to control thp

think the changelog should explain why madvise() is bad.

No problem. I wanted to keep it simple for the original submission, but
that's probably something that should be included.

This is something that we (Robin and I) had discussed a while back, and,
upon review, I'm beginning to agree that this might be the more sensible
route to take.

I'm going to try and gather a bit more data to see if we can get some
more exact answers as to why THP is performing so poorly under certain
conditions before trying to push this particular patch any further.

Thanks for the input!

- Alex
