Pyramid Single File Tasks Tutorial runs under mod_wsgi

I try to make the Pyramid Single File Tasks Tutorial runs under mod_wsgi, and figure that two changes are needed to make it runs both standalone (http://localhost:6543) and under mod_wsgi (http://localhost/task).

I would like to share these two changes:

[tasks.py]

FROM:
if __name__ == '__main__':
    # configuration settings
    settings = {}
    settings['reload_all'] = True
    settings['debug_all'] = True
    settings['mako.directories'] = os.path.join(here, 'templates')
    settings['db'] = os.path.join(here, 'tasks.db')
    # session factory
    session_factory = UnencryptedCookieSessionFactoryConfig('itsaseekreet')
    # configuration setup
    config = Configurator(settings=settings, session_factory=session_factory)
    # routes setup
    config.add_route('list', '/')
    config.add_route('new', '/new')
    config.add_route('close', '/close/{id}')
    # static view setup
    config.add_static_view('static', os.path.join(here, 'static'))
    # scan for @view_config and @subscriber decorators
    config.scan()
    # serve app
    app = config.make_wsgi_app()
    server = make_server('0.0.0.0', 8080, app)
    server.serve_forever()

TO:
def get_app():
    # configuration settings
    settings = {}
    settings['reload_all'] = True
    settings['debug_all'] = True
    settings['mako.directories'] = os.path.join(here, 'templates')
    settings['db'] = os.path.join(here, 'tasks.db')
    # session factory
    session_factory = UnencryptedCookieSessionFactoryConfig('itsaseekreet')
    # configuration setup
    config = Configurator(settings=settings, session_factory=session_factory)
    # routes setup
    config.add_route('list', '/')
    config.add_route('new', '/new')
    config.add_route('close', '/close/{id}')
    # static view setup
    config.add_static_view('static', os.path.join(here, 'static'))
    # scan for @view_config and @subscriber decorators
    config.scan()
    # serve app
    app = config.make_wsgi_app()
    return app

application = get_app()
if __name__ == '__main__':
    server = make_server('0.0.0.0', 8080, application)
    server.serve_forever()

I am using Debian 6, and the following is the relevant section in /etc/apache2/mods-enabled/wsgi.conf, where task.wsgi is a symbolic link to task.py in the same directory.
