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().
You could call sys.exitfunc() just before os._exit().
