FWIW, in mid-late July, my problems were not PREEMPTION-related.  I
tried everything I could to get usable threaded apps under XFree86, but
my Athlon XP rebooted every time I tried to run kdm, Firefox, etc.

This included all four combinations of PREEMPTION and ULE/4BSD.  Rolling
back to July 1 was the only thing that worked for me.
