If onreadystatechange is guaranteed to be called only once for readyState 3, then I don't see much point in making responseText available in this state. It seems like it will encourage the use of window.setTimeout() to poll the responseText property looking for new stuff...
It looks like Gecko implements an "onprogress" event handler for this purpose, using an event object of type LSProgressEvent (http://www.w3.org/TR/2002/WD-DOM-Level-3-LS-20020725/load-save.html#LS-LSProgressEvent)
That event listener is called each time new data arrives. Maybe that's an alternative to consider?
