  Hmm, heavy memory load... sounds familiar:  I've noticed that running
"grep foo /dev/zero &; grep foo /dev/zero &;"  will lock up my system
within a minute 100% of the time when X is running.  It used to happen
without X running, but now it only seems to happen when X is running
(which is why I thought it was fixed).  It looks like it gets stuck in a
loop and spends most or all of its time in uvmpd_scan.  I just sent in a
pr (kern/9308).  Sounds like this might possibly be what is happening to
you.
