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.
