BTW, after some further trawling in the buildfarm logs, it seem that that
"no results for" failure mode has been seen *only* on chipmunk, where it's
happened in roughly half the runs since that particular test case went in.
So it's definitely platform-specific. It's less clear whether the test
case is bogus, or it's exposing a bug added elsewhere in db5f98ab4fa44bc5,
or the bug was pre-existing but not exposed by any older test case.
