This test creates an iFrame via document.write(), then immediately changes the source of that iframe while the main document is still being parsed.  The src change should not result in a new back/forward list entry.<br>
    <script>
        document.write('<iframe id="frame" src="http://127.0.0.1:8000/navigation/resources/slow-resource.pl?delay=250" width="500" height="500"></iframe>');
        document.getElementById('frame').src = "http://127.0.0.1:8000/navigation/resources/slow-resource.pl?delay=250";
        document.getElementById('frame').onload = loadDone;
    </script>
