It seems unittest.TestSuite holds references to unittest.TestCase instances
after the test runs, until the test suite finishes. In a large suite, where
the TestCase instances consume memory during execution, that can lead to
exhausting all available memory and the OS killing the test process.
What do you think of a change like this?
