You have a point. What about CSS? At first I think it would just render funny, but some javascript actually interacts with the CSS, e.g. jQuery selectors based on style classes or something. So it has the same problem really. Images would be safe. Or an alternate plan, start rendering, but do not run the javascript until the resource checks for css+js files return. It would slow things down some more, but not as much as waiting for everything.
