I am getting a reproducible panic very soon after starting an X11 
server. Dump is available if anyone wants to hunt this down

Additional info:
I386, -current as of this morning
X11 server has not been running on this box for many months, so I don't 
know when the problem started.

panic: kernel diagnostic assertion "l->l_holdcnt == 0" failed: file 
"/m5/netbsd-current/src/sys/arch/i386/i386/syscall.c", line 165
