Summary:                    [patch] Shared IMAP mailboxes can cause the server
to crash
Description: 
If the IMAP mailbox used to hold the voice messages is shared amongst a
number of users then the server can crash with problems inside the UW-IMAP
C-Client code. This is caused by multiple threads trying to use the shared
structure that the c-client code produces for the mailbox stream.

The particular installation is using Cyrus Imap server, with
authuser/authpassword set and multiple users having the same imapuser
setting.

BlargMan: if you run asterisk in gdb and trace the code back up into
Asterisk, is the c-client call protected by a lock? It's possible that some
calls were missed.

I'm beginning to think this might be the best we can do here.
