My concern is that if the atc manager update is taking me from 60hz
down to 20hz means it could be consuming on the order of 30
milleseconds per call.  Simply calling it once every 2 seconds will
impose a 30ms hitch in the frame rate every 2 seconds which
approximately two dropped frames if you are running at 60hz.
(Individual results may vary ...)

I understand that ATC is a work in progress, but something needs to be
done before I go into a complete panic. :-)
