The only thing needed from doctest.py, AFAIU, is a custom exception
class inheriting from AssertionError, so the test runner (which does the
colorization) can distinguish doctest errors from regular assertion
failures.

It should be simple to monkey-patch this too, by setting
DocTestCase.failureException, so we can support Python 2.5 through 3.1
