Flash Player is single threaded... which is why there isn't a "sleep" command. If you slept and didn't allow other code to execute... your application would just freeze. And that's not what you want. I don't see where the problem is. If I request a url... then get the response. I could just do the next request after I got the response.
Also you just setup a Timer to request on an interval.
