New Revision: 350220

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=350220
Log:
Fix joinable thread terminating without joiner memory leak in chan_iax.c.

The iax2_process_thread() can exit without anyone waiting to join the
thread.  If noone is waiting to join the thread then a large memory leak
occurs.

* Made iax2_process_thread() deatach itself if nobody is waiting to join
the thread.
