dontkill: only use noswap flag to mark processes as not to be terminated on oom
changing procmode has the nasty side effect that notes cannot
be posted to them, prventing sysfatal() and threadexitsall()
to cleanup properly.
recent kernels also check the noswap flag to void killing them
in out of memory condition, so this is really all we need now.
