If one changes the font in the Idle Preferences dialog, all open windows are somehow notified and they immediately respond. Classes defined in extensions do not get notified. So CodeContext sets up a polling loop. Roger Serwy's line number extension (posted to #17535) copied the polling hack. It would be better to enhance the the notification mechanism to either generate an event that could be caught or setup a callback registry.
