[PATCH 1/3] [PATCH i386] during VM oom condition,kill all threads in process group
From: Will Schmidt
Date: Tue Jun 05 2007 - 13:49:00 EST
When we get into a state where VM has ran out of memory, and it's time to
thwack a process, we should take out the entire process group, rather than
just one thread.
Tested on i386
