Hmm.  Xine still works fine here.

I tried starting xine with no dvd in the drive for grins, and _without_
this patch, I had to resort to SysRq-E to regain control of my box, and
that still took quite a while.  I got no oops, but a zillion IO retries
and sector blah messages.  DoSed me bigtime.  With this patch, I just
got the expected can't open failure.
