The existing code counts the number of 401 responses in the num_401_calls authenticator attribute. This is in place so as to ensure the necessary auth header is sent, while avoiding infinite 401 loops (issue #547). This commit makes num_401_calls an instance of threading.local() (previously an integer), using num_401_calls.value as the counter. It ensures that concurrent authentication requests get each their own counter and behave as expected (otherwise every other concurrent request would have its authentication fail).
