Summary:                    Asterisk becomes unresponsive after locking 1.4.19
Description: 
We are runing a high load system using 1.4.19 and have times where asterisk
becomes completely unresponsive and will not allow any incoming or outgoing
calls to or from the system. After a "core show channels" there is no end
channel count and the CLI will become completely unresponsive. I have
attached "core show locks" output.

It would appear that the deadlock caused here is due to the fact that there
are multiple spies listening to the same channel and that a portion of
app_chanspy was written under the assumption that there would be only one
spy listening to a channel. I am working on a patch which should address
this.
