This is due to my patch that was pushed out to mitigate the massive DS  
outage in Uruguay. The patch did two things: it prevented the  
particular cause of DS malfunction that UY encountered, AND wrapped  
the entire DS initialization routine in a try/except that will, upon  
failure, move the old DS out of the way and start a clean one. It's  
basically an emergency bailout -- if we can't load the DS and we do  
nothing, the machine is unusable.
