The program runs in the background and subscribes to IMAP IDLE notifications. When the notifications arrive it can do a send/receive on the PocketOutlook account you specify, effectively enabling push email for your Gmail account (or other imap server that supports the IDLE command).

Release notes:

* Program will atttempt to connect data connection if not connected.
* Some resource leaks have been fixed, will hopefully prevent the hanging.
