    # Tests: https://github.com/thingdom/node-neo4j/issues/76
    # By waiting one second to see if the callback is called twice.
    #
    # Note that this test is explicitly *not* in Streamline syntax, so we can
    # test the use case where a regular callback throws an error instead of
    # properly propagating it (which Streamline automatically takes care of).
    #
    # This will FAIL until this issue is fixed upstream in Streamline:
    # https://github.com/Sage/streamlinejs/issues/168

        # this test passes via manual/visual verification now --
        # the error is properly thrown immediately instead of this callback
        # getting called twice.
        # but because an error is thrown, this test still fails to Mocha.
