events reported for socket
Upon first invocation (which occurs automatically when super.transmitLoop() is called, in connect(), above): * false if connect() returned a code denoting either an error or a successful connection (meaning there's no need to go into epoll wait). * true otherwise, to go into epoll wait.
Upon second invocation: * false to not return to epoll wait.
Called from super.transmitLoop() in two circumstances: 1. Upon the initial call to transmitLoop() in connect(), above. 2. After an epoll wait, upon receipt of one or more registered events.
