[Python-ideas] Test Class setup and teardown in unittest

[Guido van Rossum]

Ignoring many of the finer points brought up here, and putting
practicality before purity, I think having setUpClass and
tearDownClass methods is a great idea.

While we're at it I would also recommend adding module-level setUp and
tearDown function -- Google's extension of pyunit implements these and
they are often handy for a variety of use cases.
