Ah, yes, this is a general fuzzing issue I've been thinking about. I've
done a bit of research trying to figure out with what heuristics to
fuzz. And than it hit me: even more important than finding a "good"
long string, for example, is how to get it properly delivered. The
"test harness" + "knowledge of where the test ends up" is almost more
important than the "test" if you will.
