PIPELINE: logging URLS that fail to support pipelining heuristics

I am trying to integrate twitter into an iOS app using Ben Gottlieb's Twitter-OAuth-iPhone library. When I run this on the simulator it works fine. However, when I run it on an iPhone it does not work. I get the following messages in debugger:

> PIPELINE: logging URLS that fail to support pipelining heuristics
> PIPELINE: Heuristics failed for: twitter.com

Any ideas what is going on here, an开发者_如何学运维d how I can get this working?

I think I know what this is, but I've only seen this in iOS 5. Due to the NDA I can't give details though on here. Post it in the Apple Developer Forum and i'll answer your post once you post the link.
