Which sucks when a process like X tries to free and realloc things when possible and tries to be system friendly, but thus increases the chance to get shot down, while programs over-allocing memory and never freeing it get to survive. It's a sad world. :-P Anyway, when at our office we were running X on low-memory systems and had to reboot often because of X being killed, rendering the text console useless, we had a patch to prevent processes with specific names being killed. I could revive this and turn this into a sysctl if anyone's interested...
