Oh good, it's reproducible! :)

I'm getting the exact same symptom, Jeff -- win4lin locks up when
shutting down.  Your message had great timing ... I actually just
played around with the win4lin + preempt patches; I think I might
know what's causing it to lock up.  I'm just about to reboot, so
I'll let you know if my attempts were successful.
