// for the connection. The |receivePort| and |sendPort| conventions
// follow the same conventions as -[NSConnection initWithReceivePort:sendPort:].
// Note that due to Radar 6676818 "NSConnection leaks when initialized with nil
// sendPort" that you will leak a connection if you pass in "nil" for your
// sendPort if you are using NSPorts (mach or socket) to communicate between
// threads. The leak occurs on 10.5.6, and SL 10A286. This simple answer
// is just to always use two ports to communicate. Check out the test to see
// how we do cross thread communication.
