> Operations that update queues when shared_lastcall is set lock the queue in question, then have to lock the queues container to find the other queues with the same member.   On the other hand, __queues_show (which is called by both the CLI and AMI) does the reverse.  It locks the queues container, then iterates over the queues locking each in turn to display them.
> Deadlock.
