Summary:                    IMAP crash multiple callers / callers hangup at beep
Description: 
A multiple CPU machine + asterisk-1.4.22 + imap2004g, with more than one
user in voicemail (not the same mailbox) disconnecting right after or close
to beep + 3 seconds timeout for abandon causes, is a bad combination.  

In same cases IMAP warnings about parsing response and in most cases a
segfault. I'd like to know what the root cause is and what fixes it? I can
produce any backtraces / scenarios anyone needs to lend a hand here.

Reading the comments on this bug report are leaving me in awe. Thanks for
the thorough investigation into this problem. I can't believe that the
c-client has such thread-safety issues. That is just so bizarre. Would you
mind uploading your AST_MUTEX_STATIC changes as a patch so that they can be
reviewed and potentially merged into Asterisk? Thanks!
