Inconsistant origins are bad. Which path is supposed to be believed? 
Which path is supposed to be selected? From what point of view? None 
of these are defined conditions; non-determinism is not good for
performance. Expect some things to work, some things to be strange, 
and some to be lousy. 

Your best bet is to minimize the overlap period.
