> If a message is received that needs to be decrypted, or if a message need to be encrypted, a cipher is taken from the queue.  However, if a new coordinator concurrently sends a new secret key, it will clear and recreate the cipher queues.  If the previous operation then puts its cipher back on the queue, the queue will now contain a cipher with the old secret key.  This will result in random message decryption failures when a message encryption/decryption pulls the outdated cipher from the queue.
