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.

This "fix" went in to the production system last night. Things are stable
today so far. Could not reproduce the crash. And single threaded access
through libc-client calls to IMAP server did not appear to have a negative
affect on leaving  / listening to voice mails.

Will leave this issue open until digium accepts a proper fix. Also willing
to try to break any official patches that may come out and help to verify
this is resolved.
