After more thought, I need to push another fix for the buildfarm
failure anyway, so I can take this patch too. Sorry for going back and
forth on this. I'll push the attached 0001 patch tomorrow, barring
any objections. I tested the patch several times and confirmed it
passes every time. There's still room for improvement, though, so I'll
come back to the test patch next week and push it separately.
