In a universe where you're getting too many piglit contributions and
have you do quality control *somehow*, sure. But in this one, getting
people to write tests is like pulling teeth (and I'm guilty of this as

like it might be a losing proposition.

Yeah, patch looks perfectly fine. But I'd like to hear from Laura (or
Martin perhaps, who reviewed a lot of these) about whether this was
done on purpose or not, pending a spec fix.
