Summary:                    [patch] [regression] Call Pickup Hangs Asterisk
(deadlock?)
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.

The applicable fixes for v1.4 is the deadlock and the in progress
