Subject: [PATCH] Make unittest.removeHandler() an overloaded function.

See https://docs.python.org/3/library/unittest.html#unittest.removeHandler

- Without args it removes the signal handler.
- With a function arg it is a test decorator that temporarily removes
  the handler while the test is running.
