Heh, well - allowing multiple testcases to share fixtures like expensive
databases was one of the primary use cases given for introducing
setUpModule and setUpClass.

No, I just mean that directly creating test collections using TestSuite
is a common thing for test frameworks to do. If the base TestSuite
didn't support class / module fixtures then these test frameworks would

I think the result tagging idea will work both as a bugfix for 2.7 and
3.2. I'll work on a patch and test. If it doesn't work we can take it
to python-dev, but bearing in mind that we have to remain compatible
with the released 2.7 as well (i.e. not changing the behaviour of
