New Revision: 29693

URL: http://svn.digium.com/view/asterisk?rev=29693&view=rev
Log:
 Sanity check code for an extended failure in trying to obtain a channel lock that may have been obtained elsewhere. Prevents the monitor thread of the SIP module from going into an infinite loop, effectively, breaking SIP until you restart Asterisk.
