        NRWT: debug messages from the workers are being logged twice
        https://bugs.webkit.org/show_bug.cgi?id=60428

        It looks like when the workers are run in separate processes
        we end up getting two copies of every log message they print.
        This has to do with the multiprocessing module on UNIX cloning
        the log configuration in a way I wasn't expecting, and so two
        log handlers end up getting registered.
