That latter approach is similar to what happened with SSI's isolation
tester.  It started out in Python, and then Heikki rewrote it in C.
If Python/Ruby code is massively simpler to write than the C code,
that might be a good way to start out.  It'll be an aid to reviewers
even if neither it nor any descendent gets committed.

Frankly, I think some automated testing harness (written in C or Perl)
that could do fault-injection tests as part of the buildfarm would be
amazingly awesome.  I'm drooling just thinking about it.  But I guess
that's getting ahead of myself.
