Comment:

 Yeah, I don't think this can happen either, but guido has a pretty good
 track record, and we might as well fix all the stuff he found.  Code
 that's harmless today can become harmful tomorrow if somebody changes it
 or copies under the assumption that it was correct to start with.

 Merging to 0.3.2, no backport.
