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.

I was unable to reproduce this issue exactly, but I did experience a crash.
I placed 2 calls, both to voicemail, after beep (3+ seconds) I hung up both
calls simultaneously. From the output, it seems there is a lot of data
corruption happening, but I'm not versed enough in this to say anything.

I hope the output I uploaded (dbrooks_*.txt) is useful..
