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.
