Ah, good catch!  That would explain the 100% CPU load, then, if it gets
stuck in
this deadlock avoidance loop for forever.

Tilghman improved the "core show locks" functionality for 1.4.13 to be
able to
show threads that are stuck in a trylock loop like this.  So, hopefully
if
someone can grab that output with 1.4.13, we can see a thread stuck in a
trylock
loop like this, as well as what other thread is holding on to the lock.
