OK, but that's just a spec problem. It's trivial in implementation because  
when the resource selection algorithm was is triggered by a script, you  
can just pass along a reference to that very script.

If it doesn't, just don't ever continue with the synchronous section. Is  
there any valid case for a script never finishing? It would block all  
event handlers from running too, so in any case it's a broken page.
