\r
    The ThreadableTest class makes it easy to create a threaded\r
    client/server pair from an existing unit test. To create a\r
    new threaded class from an existing unit test, use multiple\r
    inheritance:\r
\r
        class NewClass (OldClass, ThreadableTest):\r
            pass\r
\r
    This class defines two new fixture functions with obvious\r
    purposes for overriding:\r
\r
        clientSetUp ()\r
        clientTearDown ()\r
\r
    Any new test functions within the class must then define\r
    tests in pairs, where the test name is preceeded with a\r
    '_' to indicate the client portion of the test. Ex:\r
\r
        def testFoo(self):\r
            # Server portion\r
\r
        def _testFoo(self):\r
            # Client portion\r
\r
    Any exceptions raised by the clients during their tests\r
    are caught and transferred to the main thread to alert\r
    the testing framework.\r
\r
    Note, the server setup function cannot call any blocking\r
    functions that rely on the client thread during setup,\r
    unless serverExplicitReady() is called just before\r
    the blocking call (such as in setting up a client/server\r
    connection and performing the accept() in setUp().\r
