Summary:                    Pickup hangs asterisk
Description: 
Asterisk stops to service new calls when someone tries to pickup a call by
pressing *8. Some existing calls are also terminated, although others
continue to work. I still can run any command in the console, but I can't
stop or kill Asterisk. I can kill it only with -9 flag.
I found this trouble in versions 1.8.1, 1.8.2 and SVN.

Since issue 0018906 was closed as duplicate, i'm reposting here debug
information for this bug.

I get a deadlock everytime we use *8 to pickup a call, always
reproducible. The deadlock freezes asterisk until restart. Attached are the
debug info. (Debug info attached are to distincts deadlocks of this same
problem.)
