Steve> Maybe os.exit() could be more widely advertised, though ...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 os._exit().
