Good point.  I'll change doctest, in the specific way Guido suggested.

Partly, but a minor effect:  there aren't enough doctest'ed pieces in the
test suite to account for much of that.  It's definitely the cause if you
just run test_generators.py in a loop <wink>.  Recall one of Skip's original
categories:

    * Not worth fixing, because the except: occurs in situations that
      would not affect application code (such as in module tests).
