Please consider this when writing the ECMAScript binding for DOM3 Events.

> What does DOM Events say EventListeners should have their "this" bound to?

Undefined in the spec.  All the bindings say is:

  Object EventListener
    This is an ECMAScript function reference. This method has no return value.
    The parameter is a Event object.

I guess for addEventListener and so forth we do rebind |this|, so we should do
the same for XMLHttpRequest.

Alex, please read
http://www.w3.org/TR/2000/REC-DOM-Level-2-Events-20001113/ecma-script-binding.html
carefully.
