关于Tornado的asyncHttpClient的问题，asynchttpclient,想用asyncHttpC

想用asyncHttpClient来下载xml，并用feedParser解析。代码如下

# coding:utf8from tornado.httpclient import AsyncHTTPClientfrom tornado.ioloop import IOLoopimport feedparserdef parse(response):  if response.error:    print "Error:", response.error  else:    print feedparser.parse(response.body).feed.titlehttp_client = AsyncHTTPClient()http_client.fetch("http://www.laruence.com/feed", parse)http_client.fetch("http://feed.cnblogs.com/blog/sitehome/rss", parse)http_client.fetch("http://feed.cnblogs.com/blog/u/155819/rss", parse)IOLoop.instance().start()

直接print response.body没有任何问题，但是加上feedParser来处理后，就会出现异常。似乎是解析时间过长导致的。有什么解决办法吗?
