Summary:                    Deadlock between (MOH) ast_write on one end and
local_hangup on other end (p->lock versus chan->lock_dont_use)
Description: 
If an ast_write (in this specific case from music on hold) on one end of a
local channel races with local_hangup, on the other end, a deadlock can
arise in which the ast_write end holds chan->lock_dont_use and is waiting
for p->lock and the local-hangup end has p->lock and is looping on trying
to acquire chan->lock_dont_use.
