I'm also noticing very bad behaviour wrt scheduling, I think. When I launch my
parallel cpu burning code, the system _really_ stalls, the mouse in X11 is not
jerky, it is _stuck_ for a couple or three seconds...

The only diffrecence is that, trying to solve nVidia driver problems, I disabled
BKL preemption:

werewolf:/usr/src/linux# grep PREEMPT .config
# CONFIG_PREEMPT_RCU is not set
# CONFIG_PREEMPT_NONE is not set
# CONFIG_PREEMPT_VOLUNTARY is not set
CONFIG_PREEMPT=y
# CONFIG_PREEMPT_BKL is not set
