Really the whole oom_kill process seems bass-ackwards to me. I can't in my mind
logically justify annihilating large-VM processes that have been running for
days or weeks instead of just returning ENOMEM to a process that just started
up.
We run Oracle on a development box here, and it's always the first to get the
axe (non-root process using 70-80 MB VM). Whenever someone's testing decides to
run away with memory, I usually spend the rest of the day getting intimate with
the backup files, since SIGKILLing random Oracle processes, as you might have
guessed, has a tendency to rape the entire database.
It would be nice to give immunity to certain uids, or better yet, just turn the
damn thing off entirely. I've already hacked that in...errr, out.
