Gah.

Here's the entire test case:

<iframe></iframe>
<script>
     window.onload = function() {
       window.onerror = function(msg, file, line) {
         alert('Parent handler: ' + msg + " " + file + " " + line);
       }
       frames[0].onerror = function(msg, file, line) {
         alert('Subframe handler: ' + msg + " " + file + " " + line);
       }
       frames[0].setTimeout(function() { throw "oops"; }, 100);
     }
</script>

This isn't even about origins and tainting so far; everything here is 
same-origin.  It's purely about which onerror gets called.
