Yep.  This is the one remaining problem with this whole setup.

Note that this is kinda needed for web compat no matter what we do with 
the document.open() case, by the way, because if people grab "this" and 
hand it out to some script outside the window in question and then 
navigate the window, the "some script" needs to end up having a proxy 
for the new global.
