Run a local httpserver with the given port or an ephemeral port. This function assumes it is run as a child process using multiprocessing. Args: conn: A connection to the parent process. The child process sends the local port, and waits for a message from the parent to stop

        stop serving. It also sends a "result" back to the parent -- this can
        be used to allow a client-side test to notify the server of results.
    dirname: The directory to serve. All files are accessible through
       http://localhost:<port>/path/to/filename.
    port: The port to serve on. If 0, an ephemeral port will be chosen.
    server_kwargs: A dict that will be passed as kwargs to the server.
