And may also do a bunch of stuff that he *doesn't* want, namely throwing
out any *other* error messages that might occur (like "I/O error" - yes,
I *have* had that happen, with a disk that occasionally went
offline; the appearance of "I/O error" was a signal that it was time to
run off and reset the disk - or "Connection timed out").
