We are going to start contributing tests back real soon now.  I'm not sure
that these are the best tests to contribute as they require a version of
Python to compare against rather than being nice and stand alone.  But I'm
sure we have other tests which cover this as well just not as exhaustively.  
We could also possibly check in the baseline file and then CPython could 
compare it's self to previous versions but it'd probably be a pretty
big file - so it probably shouldn't be included in the standard install
in the tests directory.
