On Maciej's request and I also think this was one of the issues Boris  
raised earlier I constructed the following testcase:


Most browsers seem to throw at some point, but they are not really  
consistent. The testcase works as follows. You have a parent browsing  
context A and a child browsing context B. The initial situation is that A  
holds document 1 and B holds document 2. When 2 is loaded 1 invokes the  
XMLHttpRequest constructor of B and then causes document 3 to be loaded in  
B. When document 3 is loaded 1 tries to initiate a request.

Internet Explorer 7 seems to throw when after 3 is loaded 1 invokes  
open(). Opera 9 seems to throw at the same stage when send() is invoked.  
Firefox 2 seems to invoke frame.contentWindow.client() when it shouldn't.  
Not sure why that happens.

Open questions are:

   1. What happens if you navigate from 3 back to 2.
   2. What happens if the base URI "essentially" stays the same.
      (No "directory" changes.)

And more I assume :-(

Also, is there any particular desired behavior for these cases?

(The testcase mentioned is work in progress.)
