I'm not quite sure what "if the User Agent is to unload the Document 
contained by the top level browsing context" means.  Does it mean "is 
about to unload, with the 'salvageable' state set to false"?   I would 
assume so.  I'm not sure how to phrase that reasonably, though.  It 
would be simple to define that one of the "unloading document cleanup 
steps" this specification defines is to change the state to "unloaded", 
but those happen after the unload event fires.

I suggest coordinating with the HTML5 editor to figure out how to define 
this properly and whether we need new hooks in the document-unloading 
process to do so...
