The following methods are overridden:
* send
* recv
To ensure that the ``zmq.NOBLOCK`` flag is set and that sending or receiving
is deferred to the hub if a ``zmq.EAGAIN`` (retry) error is raised.
The `__state_changed` method is triggered when the zmq.FD for the socket is
marked as readable and triggers the necessary read and write events (which
are waited for in the recv and send methods).
Some double underscore prefixes are used to minimize pollution of
:class:`zmq.Socket`'s namespace.
