Crash with HEAD on amd64 - in setrunnable()

[Paul Goyette <paul%whooppee.com@localhost>]

With a very current kernel, I just got this:

# crash -M /var/crash/netbsd.21.core -N /netbsd.gdb
Crash version 9.99.18, image version 9.99.18.
System panicked: kernel diagnostic assertion "lwp_locked(l, 
l->l_cpu->ci_schedstate.spc_lwplock)" failed: file 
"/build/netbsd-local/src_ro/sys/kern/kern_synch.c", line 910
Backtrace from time of crash is available.

(Obviously, I have a core dump, so I'll be happy to investigate further
if anyone has suggestions.)
