We have made the fireEvents() final in handler manager and made it
impossible for users to replace the handler manager in widget, so I think
this change would be necessary to preserve the full spirit of what we've
been doing to upgrade the user's event system.
However, we can tell people to use super-source to replace their handler
manager class instead. It is not as clean of a solution, but it will work,
and we can wait to see if anyone truly howls for this feature and put it
into gwt 2.0 instead, then it can be a cool upgrade instead :-).
Cheers,
Emily
