I was seeing typical overshoots of around 15, sometimes more.  I picked the 
number 100 out of the air as it seemed large enough to cure the problem 100% of
the time but small enough to cause no discernible side effects.  I left an
explanatory note in the code.

This is a minor tweak to resolve an irritating problem, and I hope that it in
no way conflicts with Ted's work.
