OK, so you could have a testcase where whether close() is synchronous is 
observable, but that's not nearly as bad as if close() had to return 
something that depends on the action of onbeforeunload.

The real question is what would break if close() was asynchronous? It's 
already kind of asynchronous when you close your own window...
