  On my Centrino 900MHz, it is about 0.61.

  Needless to say, this test includes the "extra large size" fonts.
For the normal size characters the speed is about twice as fast.

  If you get the MessageTally, 70% of time goes to the
BalloonEngine>>copyLoopFaster.  This is why I think Arjen's new BB
combinationRule will help here a lot.
