The SSL version of the imap4 client isnt' working under 3.0. After I
applied the patch from http://bugs.python.org/issue1210 I tried to
connect to an IMAP server over SSL. The connection hangs.

import imaplib
conn = imaplib.IMAP4_SSL("mailbox.rwth-aachen.de", 993)

After a while I stopped the attempt with CTRL+C
Traceback (most recent call last):
