What to do in response to a kernel warning

> In practice, currently, the Linux kernel kills processes on oops. OOM killer kills processes. grsecurity also kills processes.

Well...

1. oops is pretty darned unusual, in my experience.
2. OOM killing is both unusual and at least tries* to target processes that might possibly be responsible for the OOM condition.
3. I have no idea about grsecurity, but it's not part of Linus's tree, so I frankly don't care what it does.

* There is a difference between trying and succeeding, of course.
