OK, so sounds like the fix isn't a big deal, but it also sounds like the
fault injection code has come up as needing special attention a few
times during this work now.

In retrospect I wonder if it's worth the trouble.  It's very
special-purpose stuff and if nobody's using it then maybe we could just
remove it....
