That would be great. But was always a hot topic and AFAIK no solution 
was found yet.
I remember there was a proposal for a more intelligent oom killer system 
on lkml some time ago. No idea if this is still around.
(Was afaik some preemtive notification to userspace)

Intuitively the answer is clear. Kill the culprit and not just something 
big. But what is to kill? And how to determine without allocating any 
more memory...
I have never seen any craceful oom killer yet.
