 It is recommended to use this non-blocking mode in order to get the
 best scalability and performance in your application. If you need to perform
 a similar blocking connection as before (version 0.13), you can call to [`connect_sync()`](https://docs.rs/message-io/latest/message_io/network/struct.NetworkController.html#method.connect_sync).
 Note also that the previous `NetEvent::Connect` has been renamed to `NetEvent::Accepted`.
 The current `NetEvent::Connect` is a new event to deal with the new non-blocking connections.
