This kind of test is a "poster child" for why doctests with lots of
output are fragile:  even though it uses pprint, it *still* fails on
different Python versions (i.e., it is breaking on Python 2.4).

This test needs to be rewritten either as a traditional unittest (my
preference), or the assertions about the state need to be rewritten in
"fine grained" form.
