Hanging folder list w/cyrus mini-patch

[David Kerry]

Hi Folks,

	I've been using imp 3.0 with cyrus here for a little bit and banging
my head on the problem of the folder list just plain hanging indefinitely (
and running cpu > 90% and killing cyrus at the same time).  The problem was
that the mailbox list was getting two 'INBOX'es in it and the tree iteration
code was tripping over the second one and looping.

	I saw other people with the same problem, but I saw no replies with
patches or workarounds.  So... I finally tracked down the problem and came
up with a little patch (see below).  This works for me, but may break other
imap servers or configurations.
