FWIW, I ran your code using python 2.3.4 on linux with the following 
modifications, and it worked fine (no failing tests out of 9):

1- added 'from sets import Set as set' since set() isn't built in in 2.3
2- changed True back to False in the following test:

>         '''Creates a new _Check_point instance; appends it to .data.

>         >>> print Wall_clock.is_instanced
>         True


3- omitted the optionflags=doctest.ELLIPSIS argument from the following 
code, since it's not available in python 2.3's doctest:

>     doctest.testmod(sys.modules[__name__], report = True,
>                            optionflags = doctest.ELLIPSIS)

Running the same code with 2.4 gave 3 failures out of 9 tests.
