AFAIR we only intended that message as a temporary measure until we'd
figured out why things seemed to be failing on Windows. If there's no
longer a need, I'd vote for removing the whole code chunk, not just
stepping the level down by one. But if you are still seeing it, maybe
we haven't figured out why the failure?
