Aah, ok. The spec already says that's not allowed. You can't get to the 
History object of a cross-origin Window:


(I forget what the story is if you get a History object from a same-origin 
Window, then have the browsing context navigated, then use the History 
object you kept around... I expect it is supposed to work much as if you 
were to call it on the new, cross-origin, History object, though.)

Things that are impossible just take longer.   `._.-(,_..'--(,_..'`-.;.'
