The problem isn't whether it's good or bad to have the kernel do something about OOM conditions, but what "the Right Thing" is.
If your solution involves killing the "guilty" program, that's awfully hard to define in a generic way. A human admin can figure it out, but it's a much harder task to teach the computer to make that same judgment. Since we want the computer to never make mistakes, (i.e. killing something important) our job is doubly hard.
I suspect that once we get a good algorithm for determining what the "guilty" process is, it'll become a matter of mere implementation details. Implementation details like "kernel or userland", for example. :) -- = Warren -- ICBM Address: 36.8274040 N, 108.0204086 W, alt. 1714m
