That was a 2.6.13 kernel, but the last one I had was with 2.6.15 before I 
changed to -j1

The unusual part was, that kwin was killed so late. Normaly it starts with 
killing kwin - which is pretty annoying....

This are the ooms, I saved (and which hit me hard, because I was doing stuff 
in KDE when oom went on its rampage.) The ones hitting the box while I was 
sleeping and the computer doing nothing else than emerging are not saved ...
