I'd argue perhaps that "easy fix" should have read "hack", and
that this doesn't fit my condition of "most sane situations".

Would you say that this "fix" was really an elegant solution,
or just a quick hack?  I don't think deleting things from
sys.modules has defined, guaranteed behaviour, so I'm uncertain
whether anyone should rely on it working.  I still think
Colin's approach is a generally okay one.
