Well, with crrent versions you have to have 2 or 3 of them to realy make a server trtash. Something like:
tail /dev/zero
recovers with the oom killer
tail /dev/zero & tail /dev/zero & tail /dev/zero
will most likely trash for minutes.
Some kind of penalty could be introduced, because this is better to set up than ulimit. On a system with large amounts of users you simply cant set the ulimit of a single user to mainram/concurrent-users or mainram/concurrent-evil-users.
