Right now, when doing a test case, one must clear all the variables created in the test class, and I believe this shouldn't be needed...

E.g.:

class Test(TestCase):
  def setUp(self):
    self.obj1 = MyObject()

  ...

  def tearDown(self):
    del self.obj1

Ideally (in my view), right after running the test, it should be garbage-collected and the explicit tearDown wouldn't be needed (as the test would garbage-collected, that reference would automatically die), because this is currently very error prone... (and probably a source of leaks for any sufficiently big test suite).

If that's accepted, I can provide a patch.
