Thanks, Thomas. I actually had 26 /dev/sg's, which should have been
sufficient. As expected, rounding up to 32 didn't help.
I did a little more experimenting, though, and this might be
interesting. If I remove _all_ the devices on scsi0, cdrecord
-scanbus does the right thing.

But if I put back even a scsi tape device, I have the problem again.
