__getstate__ trouble

Issues when the name argument of ViewerAppProxy.getattr is either getstate or setstate.
(I'm guessing deadlock is occurring. )

I solved it by throwing an exception for these names.

    def __getattr__(self, name):
        """Redirect method calls to the sub-process.

        Arguments:
            name {str} -- attribute name

        Returns:
            callable -- an application method wrapper
        """
        if name.startswith("__"):
            return self.__getattribute__(name)  # raise AttributeError

        def _send(*args, **kwargs):
            self._host_conn.send((name, args, kwargs))
            reply = self._host_conn.recv()
            if isinstance(reply, Exception):
                raise reply
            return reply

        return _send

Thanks for reading.
