Which is why the solution is two-part: * An OOM killer good enough to handle the "some process went insane" case. From all accounts, Rik's patch does this well. * Comprehensive per-uid resource accounting (the beancounting work) to guard against malicious users. This would be great for 2.5 (but, of course, that was said about 2.3 as well..) A full implementation would also fix DoSes against users using kernel memory (network buffers, page table mappings) which is a lot nastier than simple VM exhaustion.
