Indeed.  I believe any code which calls atexit.register.

That would be os._exit().  Calling it avoids calls to exit functions
registered with atexit.register().  I believe it is both safe, and
reasonable programming practice for modules to register exit functions.
Both the logging and multiprocessing modules call it.  It's incumbent on the
application programmer to know these details of the modules the app uses
(perhaps indirectly) to know whether or not it's safe/wise to call
