Summary:                    Local dial with moh causes crash
Description: 
When a call using dial local/ goes into musiconhold, and then the sip
extension initiating this call puts it on hold (more musiconhold) asterisk
enters a "crashed" state. any attempt from CLI to "show channels" will kill
the CLI. manager API slows down to an unusable rate. CPU load remains
normal. Asterisk can not be restarted or shutdown from the cli, soft hangup
is non functional. The only resolve is to "Kill -9" asterisk.

This problem appears to exist in asterisk 1.2.18 and 1.4.17(the versions I
have handy).

This crash can be reproduce with the aid of the following dial plan

exten => 400,1,answer
exten => 400,2,dial(local/401)

exten => 401,1,answer
exten => 401,2,musiconhold()

from a SIP phone dial 400, you hear music. Put the call on hold, about 4
seconds later asterisk has entered the above state.

Prevents local channels from playing MOH at each other which was causing
ast_generic_bridge to loop much faster.
