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.
