        If :mod:`webapp2_extras.local` is available, the app and request
        class attributes are assigned to a proxy object that returns them
        using thread-local, making the application thread-safe. This can also
        be used in environments that don't support threading.

        If :mod:`webapp2_extras.local` is not available, app and request will
        be assigned directly as class attributes. This should only be used in
        non-threaded environments (e.g., App Engine Python 2.5).
