It could be this was fixed by Alan's commit last night to fix locking in
VM.  In any case, here's the panic anyway.  This is from box2, again,
-current from last night, nfs root via pxeboot, GENERIC, spinning {boot,
buildkernel}.  I'll update the two boxes when I get back from the hospital
later today.
