        When xend starts, it fires off xcs.  If you're running on a slow
        machine its possible that xcs started but xend didnt wait long 
        enough to notice.  The attached patch loops several times while 
        waiting for xcs to come up.  It seems to be working here while the 
        original is not (slow machine here).
