Summary: Crash in local_queue_frame trying to trylock a
corrupted p->owner lock
Description:
It appears that local_queue_frame() is trying to lock a mutex that has been
destroyed (or is otherwise corrupt). The reentrancy value is 7903722 and
the pthread struct contains a value __m_owner = 0xbad, which is probably a
magic cookie for a mutex that has been destroyed.
In frame 1, isoutbound is 1, making other p->owner, making the corrupted
lock &p->owner->lock.

I was. I turned off all the debugging options the other day after studying
lock.h -- it looks like the debugging code is vulnerable to a number of
race conditions.
