> Similar to QPID-4262 and discovered via code review while investigating the other issue,
it appears that it is possible for the priority queue's "messages" deques to become out-of-sync
with their backing "fifo" deque if "PriorityQueue::setPosition" is invoked.  That method will
delete messages from the backing MessageDeque collection without removing the pointers to
the deleted messages from the PriorityQueue.
> The HA and replication plugins can both invoke this method on a queue.
