In the "cross-origin" test, the load that's happening is that of 
"http://another.domain.libpr0n.com/pass" while the form action is 
"http://www.hixie.ch/tests/adhoc/html/navigation/unload/cross-origin/pass" 
as far as I can tell.  Those are not same-origin, right?

Aha.  Perfect, thanks.  The text in the spec had just made it sound like 
the async phase happened _after_ one started parsing the new document. 
Good to know that's not the case.
