Question

我将龙卷风作为HTTPServer运行，并在gc.garbage中发现了大量的垃圾，但不知道如何清除和避免内存泄漏？谢谢你的帮助。

application = tornado.web.Application([
    (r"/webapi/", MainHandler, dict(db=db_conn)),
    (r"/web/(.*)", tornado.web.StaticFileHandler, {"path":os.path.join(os.path.dirname(__file__)) + '/web'}),
])

http_server = tornado.httpserver.HTTPServer(application, xheaders=True)
http_server.bind(options.port, options.host)
http_server.start(options.processes)

tornado.ioloop.IOLoop.current().start()

这是垃圾输出代码：

for x in gc.garbage:
    s = str(x)
    if len(s) > 80: print s[:77] + "..."
    print type(x), "\n  ", s

龙卷风gc.garbage输出如下：
