Hadn't paid much attention at the time, but yeah, it looks like Andres
tripped over some variant of this.
I'd be kind of inclined to remove this test script altogether, on the
grounds that it's wasting cycles on a function that doesn't really
do what is claimed (and we should remove the documentation claim, too).
Having said that, it's still true that this test has been stable in
the buildfarm. Andres explained what he had to perturb to make it
fail, so I'm still interested in what Horiguchi-san did to break it.
