Is this the right thing to do? Putting the test-suite aside for the
moment, if I have a loop device on a file and I hit a real error on the
storage backing that file, I don't see why detaching the loop device
from the file should clear the error.

I'm really tempted to say that we should fix the test-suite to consume
the error; once it's been read by at least one reader, it won't go back
to zero, but neither will it show up for new readers.
