Just as a followup note, I'm now trying this disc with cdda2wav, and
it's having much less trouble:

That's three errors, all retried successfully, versus hundreds for
cdparanoia.  I've not verified the audio quality yet, but I'm reasonably
confident that it should be fine.  Generally speaking I'm going to stick
with cdparanoia, but it definitely has major trouble with some discs.

Brian.
