That all looks very nice, but I wonder how many people are actually
using these things.  The injection framework itself doesn't seem to
have had a lot of uptake.

I wonder if we could improve things by adding an easy-to-run testing
script which identifies all the available error-injection inputs,
exercises them and then reports on the result?

Such a script would logically reside under ./tests/fault-injection/,
but we still don't have a tests/ directory.  Which perhaps tells us
something ;)
