Screen.start() and Screen.stop() are now official parts of the API. If
you need to pass arguments to your function I suggest calling those
methods yourself. I am planning to add at least one more parameter to
the start() method, and I don't like the idea of mixing user parameters
and Urwid parameters at the same level.
If you really want to be able to use the run_wrapper() method and pass
in parameters, I could add the user parameters like this:
def run_wrapper(self, fn, fn_args=[], fn_kwargs={},
alternate_buffer=True):
