	I got another vnlock deadlock on another server. I think it's
	different from the ones previsouly reported because this system isn't
	SMP, and it happened while a dump -X was running. I suspect a locking
	issue in fss(4), I have a core dump available if someone wants to
	help me to look at this.
	I think this happened on another system without nullfs mounts but
	where I was also running dump -X. The result was the same ("proc -
	table is full") but I'm not the one who rebooted it so I didn't
	have a chance to look at the processes in ddb.
	run dump -X on an active filesystem ?
	please :)
