Welcome to the club; I've been having them on my -curent builder since Aug
4. I'm going to set up a duplicate box and start binary-searching for the
offending commit(s).

Preemption is the default, disabled.

My box is a dual-600MHz P3 with 1GB RAM and running kde. A make -j3
buildworld will lock it up 75% of the time. It'll survive a nonparallel
build, and it'll survive a kernel build.

Haven't tried WITNESS+INVARIANTS yet since it really dogs the machine. :)
