 All I can say is that I could never reproduce it and still can't. I just
ran the test 5000 times piping it to

        egrev -v '2 tests succeeded|no errors detected|^$'

and it hasn't produced any output. So while it's not entirely satisfying
that we still don't have an explanation for the original failure, I don't
see what else can we do but move on if the problem doesn't appear anywhere
any more.
