HTML actually uses incumbent settings objects in most cases, I believe; 
the entry settings cases are the ones imposed by compat constraints.

Say you have a web page like so:

   <iframe src="foo.html"></iframe>
     onload = function() {

and foo.html has:

     function f() {
       // do something

then "do something" has the main web page as the entry settings object 
but foo.html as the incumbent settings object.  So if "f" did a location 
set, for example, the base URI for that string would be the main web 
page (because Location uses the entry settings object for the base URI), 
which is a bizarre non-local effect that I don't think we should be 
duplicating for other APIs...
