+ ``sys.modules[__name__]`` is updated with a temporary module object for the
+ module being executed. Both ``sys.argv[0]`` and ``sys.modules[__name__]``
+ are restored to their original values before the function returns.
Note that this manipulation of :mod:`sys` is not thread-safe. Other threads may
see the partially initialised module, as well as the altered list of arguments.
