It rarely gets to multiuser, and even if it does, it panics very
shortly afterward:
panic: vm_page_alloc: page 0xc0805db0 is wired

I did finally get around to dumping the vm_page struct for it (the
CTF crazyness) and I did send it to alc and kib, but neither one has
replied...

here is a dump in case someone else has some vm_page clue:
{'act_count': '\x00',
 'aflags': '\x00',
 'busy_lock': 1,
 'dirty': '\xff',
 'flags': 0,
 'hold_count': 0,
 'listq': {'tqe_next': 0xc0805e00, 'tqe_prev': 0xc06d18a0},
 'md': {'pv_kva': 3235856384,
        'pv_list': {'tqh_first': 0x0, 'tqh_last': 0xc0805de0},
        'pv_memattr': '\x00',
        'pvh_attrs': 0},
 'object': 0xc06d1878,
 'oflags': '\x04',
 'order': '\t',
 'phys_addr': 17776640,
 'pindex': 3572,
 'plinks': {'memguard': {'p': 0, 'v': 3228376932},
            'q': {'tqe_next': 0x0, 'tqe_prev': 0xc06d1f64},
            's': {'pv': 0xc06d1f64, 'ss': {'sle_next': 0x0}}},
 'pool': '\x00',
 'queue': '\xff',
 'segind': '\x01',
 'valid': '\xff',
 'wire_count': 1}

and as you can see, wire_count is not 0...  but looks resonable...

So, I'm blocked until someone w/ clue tells me what more I need to do
to debug this...
