        Customer found that when PermSize and MaxPermSize were made
        large, even though most of this space was not actually
        used, scavenge times went up dramatically when using the
        ParNew+CMS collectors. The problem was not present when
        DefNew+CMS was used, nor was it present with just ParNew.
