Hi, Kame.

I looked over the patch series.
It's rather big change of OOM.
I see you and David want to make OOM fresh from scratch.
But, It makes for testers to test harder.

I like your idea of fork-bomb detector.
Don't we use it without big change of as-is OOM heuristic?

Anyway,I need time to dive the code and test it.
Maybe weekend.

Thanks for great effort. :)
