---------------------------------------------------------------------- 
I don't see a dead lock here. One thread holds two locks and isn't waiting
on any other locks... And the other two threads are waiting on one of the
locks the first one has, but I don't see anything obvious that is
preventing that thread from giving up the lock.

Also, how is this a "forced crash". Are there steps we can use to
reproduce this behavior?
