This is true, and I see your point. However, I would think that the loading could be spread across several frames. I'm pretty sure what's happening is that all of the loading is happening all at once, which is locking the Flash Player into a single frame until all of the processing is complete. If the loading were to be spread out the application should appear more responsive. All of the loading from the api is getting done when that first Map is added to the stage.
