Is it true that in the flash/air player the actionscripts are all run in a single thread? Are all those event listeners invoked one by one and never overlap? If not, is there a way I can worry about it?

AFAIK, in ActionScript a block of code is always single threaded. i.e. it always blocks the execution of others until finished. If I am not mistaken the only time the Flash runtime executes code in a separate thread is when it is making network calls.
In the AS event model, the events do not overlap; i.e. there is no way two event listeners will be called simultaneously. They will always be executed one after the other; and this holds even for events resulting from network calls.
You would have a hard time estimating the order of the events in the cases where you have many separate events however; because most of the event model is tightly integrated to the display list. In such cases it would be best to devise some kind of a queue system first.
