Summary:                    bad magic number : loops indefinitly
Description: 
Hi,

Every now and again (i.e. after a few days), we have the following message
that displays indefinitly :

ERROR[9933]: astobj2.c:116 INTERNAL_OBJ: bad magic number 0x0 for
0x21c1508.

Eventhough, we had a similar error in the past, it seems that this one is
different. Not withstanding the fact that the previous "bad majic number"
error had its symptomes fixed but not the cause.

Have attached a core dump at the time it happened.

Cheers,

ast_do_masquerade. Keep channels ao2_container locked while unlink and
linking channels.

Previously, Masquerade would unlock 'original' and 'clonechan' and allow
another masq thread to run.
End result would be corrupted memory, and the frequent report 'Bad Magic
Number'.
