Actually ... that turns out to not be the problem.  The thread is killed
and the wait queue empty by the time the condition variable is
finalized.

Bizzarely, what appears to be happening is that rb_queue_alloc is
getting called when creating mutexes and condition variables.  Hence
free_queue is getting called when mutexes and condition variables are
destroyed, and chaos ensues.

At least it's a simple problem, but it's a WEIRD one.
