Yeah, read the presentation several times, thus the short penalty times, 
and probably high thresholds.

The idea for me is to limit the harm of excessive flapping while not 
being paranoid. I've had a customer lose a lot of connectivity for 30 
minutes after 3 or 4 flaps. I figure 5 minute ignore after about 10 
flaps in a  10 minute period.
