<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">You're setting yourself up for deadlocks here by keeping the channel locked while a separate thread executes application/dialplan.
Also, I don't see where the corresponding ast_channel_unlock() is (excepting when thread creation fail)</pre>

It's so that the caller can specifically block that thread, I wager.</pre>
