In terms of the ProgressEvents spec the 'loadend' event would be dispatched following either of 'abort', 'load' or 'error', and there must be exactly one 'loadend' event dispatched. In the Event definitions table it would look like this:

I would be in support of adding such an event. And I agree with Garrett 
that it makes more sense to dispatch it before the load/abort/error 
event is dispatched. In fact, we could even make the default behavior of 
the loadend event be dispatching one of the above three, thus allowing 
them to be canceled by calling .preventDefault on the loadend event.

Would be interested to hear Ollis feedback given that he recently 
implemented progress events for XHR in firefox.
