I misread the original message.  Running the 'def' block does indeed
leak a reference and collect() has no effect.  Similarly:

        [23154 refs]
        >>> def conjoin(gs):
        ...     def gen():
        ...         gs      # unbreakable cycle
        ...         gen     # unless one is commented out
        ... 
        [23194 refs]
        >>> del conjoin
        [23155 refs]
