There is no need to connect signals twice, can connect them directly to the helper UI loop and skip the surface loop. Then let the server decide if it is necessary to call lws_cancel_service() or not. Also rename WebsocketsServer::should_request_write() to read_blocks_event_loop() it makes more sense for the caller now on-demand write logic is completely implemented by the server class.
