Setting sync_request_timeout when remote calls a local function.

[jchan-legendpower]

I have the following setup where I patch certain modules on my remote server to use local modules:

        self.logger.info("Connecting to RPyC server on Pi")
        conn = rpyc.classic.connect(
            self._connector.addr
        )
        conn._config["sync_request_timeout"] = 600
        conn.root.getconn()._config["sync_request_timeout"] = 600
        # This is needed so that the host can serve requests to run code from the Pi
        _ = rpyc.BgServingThread(conn)

        self.logger.info("Uploading legend_test module")
        rpyc.classic.upload_module(conn, legend_test)

        # Some modules must always be run on the host even when called from the Pi
        self.logger.info("Patching modules")
        conn.modules.sys.modules[
            "legend_test.log_utils.logger_manager"
        ] = legend_test.log_utils.logger_manager
        conn.modules.sys.modules[
            "legend_test.utils.data_recorder"
        ] = legend_test.utils.data_recorder
        conn.modules.sys.modules["legend_test.utils.timer"] = legend_test.utils.timer

This works as expected like described in https://rpyc.readthedocs.io/en/latest/tutorial/tut4.html

However, I've that when my remote calls a function to be run locally, the request timeout still seems to be 30 seconds despite what I've set above. I still get:

I'm not sure how to force this timeout to be longer.
