I've also seen this behaviour in both 5.x and 6.0 (I can't recall if
it bit me in 4.x).  In my case, the trigger is OpenOffice.org - one
of the offending processes is almost always OOo/program/pagein.
Unfortunately, I haven't been able to get to the bottom of this (and
my son isn't happy that OOo keeps deadlocking on him).
