New Revision: 131072

URL: http://svn.digium.com/view/asterisk?view=rev&rev=131072
Log:
Fix a couple of places in res_agi where the agi_commands lock would not be
released, causing a deadlock.  (Reported by mvanbaak in #asterisk-dev,
discovered by bbryant's change to the lock tracking code to yell at you
if a thread exits with a lock still held)
