        # FallbackHandler： A RequestHandler that wraps another HTTP server callback. 
        # http://www.tornadoweb.org/en/stable/web.html#tornado.web.FallbackHandler
        [('.*', tornado.web.FallbackHandler, dict(fallback=wsgi_app)),
        ])
    
    # HTTPServer is a very basic connection handler. It parses the request headers and body
    server = tornado.httpserver.HTTPServer(tornado_app)
    server.listen(port)
    tornado.ioloop.IOLoop.instance().start()
 
 
if __name__ == '__main__':
    try:
        import setproctitle
        setproctitle.setproctitle('www:' + sys.argv[1])
    except ImportError:
        pass
    main(int(sys.argv[1]))

基本思想：利用 tornado 的 http server，处理消息请求。

官方文档有介绍：

• WSGIContainer lets you run other WSGI applications and frameworks on the Tornado HTTP server. For example, with this class you can mix Django and Tornado handlers in a single server.
