Summary:                    app_voicemail leaves sockets in close wait.
Description: 
app_voicemail is not closing imap sockets and they are going into
CLOSE_WAIT.
I am using imap-2006j
open files seem to go up during busy times but never drop.
my asterisk-vm process does not notify it is only there to isolate
recording and playback of voice mail from the rest of asterisk.
my asterisk process forwards to asterisk-vm in the case of busy/noanswer
or checking voicemail.
in 50 hours I have generated 
836 handles in CLOSE_WAIT all to imap
33 handles in ESTABLISHED 1 mysql 32 imap
12 udp handles

Okay, on further examination, it appears that the IMAP support in
app_voicemail is one huge resource leak, which cannot be easily remedied. 
It engages in sharing of resources, migration of multiple pointers which
are copied between structures, etc.  It's clear from the implementation
that this was done for the purpose of making IMAP support very fast. 
Unfortunately, the code also leaks like a sieve.  In fact, the way it's
written, I'm surprised that it doesn't constantly blow up.
