AIUI from chat, the idea is to increase the probability that if the
testing causes something bogus to happen, the bogus behavior will
result in an easily identifiable abort.
This seems like a valid line of reasoning; all the same, implementing
such a tool is a fairly big (and annoying) pile of grunt work. Plus
various variations on it have been done before. (Some of which might
be worth looking into, actually.)
