SubjectRe: [2.4.17/18pre] VM and swap - it's really unusable

-rmap is 2.5 stuff.

I would really like to integrate -aa stuff as soon as I can understand
_why_ Andrea is doing those changes.

Note that people will _always_ complain about VM: It will always be
possible to optimize it to some case and cause harm to other cases.

I'm not saying that VM is perfect right now: It for sure has problems.

AFAIK Andrew's code simply adds schedule points around the kernel, right?

If so, nope, I do not plan to integrate it.

2.5 stuff.
