---------------------------------------------------------------

another lockup today.
luckily was running debug today:)

Note: at the end of iax-coreshowlocks-may08-auckland the idle threads, normally there are 10.

edit 3rd June 2013 added below:  The releasing of channels is normally only done by one side, except when we lockup.

> Intermittently all IAX calls stop over the trunk.
> I think this is reproduced when a call is transferred back to the originating site, we have "transfer=on"

> Attached are the 1.8.15.0 lockup, and the 11-branch lockup.
