That has a "reverting the commit fixes it", and a confirmation from Nick 
Bowler.

Eric, Carl: should I just revert that commit? Or do you have a fix?

I'm not aware of any real fix here. That commit isn't supposed to change
much, but it clearly unmasks some broken driver code.

So reverting it for now to hide the broken code from poor users does
seem a good plan to me, (unless Eric has any updates or alternate
suggestions).
