"Access Denied" when calling PublishAction from multi-threaded code?

I am trying to use multithreading to spead up the page in my site. For a certain action on my facebook app, I need call PublishAction multiple times, so I figured I could create a new thread and return the page, but I am getting an "Access Denied" error when doing this. Any ideas why?
