While you are at that...

I'm experiencing random segfaults of user programs. Not often,
but it happens. This is a "make" mostly, sometimes a shell
running non-interactively. Sometimes a part of the xfce4
desktop dies. Randomly, as said - not reproducible.
This does never happen if I keep the CPUs (this is a dual-core
i386) under load (what I usually do, running setiathome).
So something near the idle-loop?

best regards
