I'm not sure it actually will; Olli had some concerns about event 
dispatch in the responseXML if it's tied to the old window, not the new 
one, for example.  Not sure to what extent those are 
Gecko-implementation-specific.

Note that in Gecko the old window is in fact unhooked from the document 
during open(), to prevent memory leaks; we _may_ be able to change that, 
but it's not clear.
