OK, riddle me this. If this test is a crummy test, just how is it
that I was able to warn Rik in advance that when 2.4.5 was released,
he should expect complaints? How did I _know_ that? The answer is
that I fiddle with Rik's code a lot, and I test with this test because
it tells me a lot. It may not tell you anything, but it does me.
