I am getting tired of this level of argumentation. oom_reaper in its
current form is a step forward. I have acknowledged there are possible
improvements doable on top but I do not see them necessary for the core
part being merged. I am not trying to rush this in because I am very
well aware of how subtle and complex all the interactions might be.
So please stop your "we must have it all at once" attitude. This is
nothing we have to rush in. We are not talking about a regression which
has to be absolutely fixed in few days.
