<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">By removing the queues lock, it is now possible for the container to change while we iterate. The ao2_iterators appear to account for changes to the container while iteration is talking place, but please make sure that this new behavior won't cause any unintended side effects. Beyond that, this looks good.</pre>

1)the queues container is locked when calling channels this causes a deadlock and is unneeded.
2)lock the queues container when running queue_update to maintain correct locking order.</pre>
