test_tools.test_sundry() now uses an unittest mock to prevent the logging module to register a real "atfork" function which kept the logging module dictionary alive. So the logging module can be properly unloaded. Previously, the logging module was loaded before test_sundry(), but it's no longer the case since recent test_tools sub-tests removals.
