1. If the difference between unittest and unittest2 is strictly a matter 
of deletions and addition, replace unittest with the union of the two.

2. Put the try/except dance in a compat file. Then everywhere else 'from 
compat import unittest'. This idea is one of those used to write code 
that will run on both 2.x and 3.x
