It was catastrophe. :) X crashed (or killed) with all the programs, but my little program was alive for 20 minutes (see timestamps). And for that time computer was completely unusable. Couldn't even get the console via ssh. Rally embarrassing for a modern OS to get destroyed by a 5 lines of C run as an ordinary user. Luckily screen was still alive, oomk usually kills it also. See for yourself: dmesg: http://pastebin.com/f3f83738a messages: http://pastebin.com/f2091110a (CCing to lklm again... I just want people to see the logs.)
