Very unfortunate things happen if we add an iax_frame to the frame queue and let go of the lock before scheduling the frame's transmit... There is a race condition that exists where the frame can be removed from the frame_queue and freed before the transmit is scheduled if we do not hold on to that lock. This results in a freed frame being scheduled for transmit later. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@263151 65c4cc65-6c06-0410-ace0-fbb531ad65f3
