it doesn't ping the server, it sends a IMAP NOOP command which is
supposed to prevent the server from closing the connection (lets the
server know we are still there). It also tells us of updates.

should force a disconnect (there's a few code paths where that doesn't
work, but for the most part it should)

sounds like your network is flaky and/or your imap server :-(
