Summary:                    [patch] 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.

    Update imapstorage.txt documentation.
    Updated the imapstorage.txt documentation to reflect that issues with
    c-client versions older than 2007 seem to cause crashing issues that
    are not seen with more recent versions. Documentation has been updated
    to reflect this.
