* The BMP session is managed by a simple state machine with three states: Idle
* (!started, !sk), Connect (!started, sk active), and Established (started). It
* has three events: connect successfull (Connect -> Established), socket error
* has three events: connect successful (Connect -> Established), socket error
* (any -> Idle), and connect timeout (Idle/Connect -> Connect, resetting the
* TCP socket).
