This happens because IDLE is no longer advertised in CAPABILITY before
login. This is the only widely used IMAP client I know of that has this
problem now. Wonder if RIM would have any interest in fixing this
themselves.. Probably not. Maybe I should just give up and put IDLE into
the pre-login capability..

The reason why it keeps the connection open is to give users
instantaneous notifications of new mails.
