The web has a requirement that if I have a pointer to a cross-origin 
window "win" then doing will find child windows of it with 
name="name".  See 
for what happened when we tried to disallow this in Firefox.

Now this could be implemented by having "win" be a cross-process proxy 
and having the get be a blocking RPC call that returns another 
cross-process proxy... maybe.  Deadlock hazards abound.
