Why doesn't UserGestureIndicator do this work for us?  If we're already processing a user gesture, perhaps the UserGestureIndicator shouldn't bump the count in the token...  Maybe that should be an option in the constructor?

That's a good question.

I guess that doing this by default won't work, e.g. when we run a nested message loop with a indicator on the stack during a showModalDialog() call.

I need to think of a good name for an additional enum
