I said that actionscript is single threaded. Some API calls are asynchronous and non-blocking, but for sure, when you execute one statement in actionscript, that statement and the statement after will be executed without interruption. If the statement invokes an asynchronous operation, the results may not come back for a while, but when it does, whatever statements you are executing at the time will not be interrupted

Alex, That statement is often repeated, but I believe that it is incorrect. The main thread is responsible for rendering and AMF deserialization. URLLoader runs in its own thread. Pixel Bender runs in its own thread (http://www.jamesward.com/blog/2009/04/29/announcing-pbjas-an-actionscript-3-pixel-bender-shader-library/) I have asked for AMF deserialization be moved to another thread (http://bugs.adobe.com/jira/browse/FP-2398) It would be great if better documentation on the Flash player's threads was available.
