I think it impacts the proposal to allow the oom reaper to operate over 
several different mm's in its list without processing one, waiting to give 
up, removing it, and moving on to the next one.  It doesn't impact the 
cgroup-aware oom killer extension that I made other than trivial patch 
conflicts.  I think if we can iterate over the oom reaper list to 
determine inflight victims it's simpler.
