Review request for Nepomuk, Soprano and Sebastian Trueg.


    Virtuoso doesn't support empty graphs, so we use a fake graph which acts
    as the default empty graph.
    This approach, while useful, does have a performance impact, as the
    graph needs to be regularly checked agains't this default graph.
    Therefore, we add an option to disable this feature. By default, this
    feature is enabled in order to preserve compatibility.
