   I think you misunderstood what I was (trying to) say. I mean that  
it is very difficult to implement looping cleanly in *JavaScript*  
because of callback latency, single threaded interpreters, etc.

   I think looping is useful and common enough that we should have an  
attribute for it, and thus make the implementation the responsibility  
of the UA/media engine.
