That sounds wrong, but I seem to recall that if weights are involved then the container would be locked for some reason. I'm not 100% sure though.
Ill look into this closer</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The lock was added here after ring_one in commit 5225 by markster it was changed to need_weight recently as a local copy of use_weight to avoid deadlock on reload when a incoming call arrived while reloading.
i dont see any need for holding the queues container while dialing out ... </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>
