Yes, yes, this is a CD- but cd9660 would still get unhappy if things change
out from under it.

I've been coming around to the more traditional view- until we have a
mechanism that does strong device revalidation, we should probably report an
error back to the caller so that UVM/UBC wll not silently pick up a bunch of
'different' pages.
