one followup:

when attempting to shut down the system after getting the:

	vm_object_deallocate: unreferenced object still paging

the system crashed at 

0xf818764c <ufs_inactive+48>:	cmpw   $0x0,0x54(%edi)

which appears to be the "ip->i_mode == 0" in the following:

	/* Get rid of inodes related to stale file handles. */
	if (ip->i_mode == 0) {
		if ((vp->v_flag & VXLOCK) == 0)
			vgone(vp);
		return (0);
	}

%edi was NULL; somehow there was a vnode for which VTOI returned NULL..
