Oh btw, it's best to have two params - the minimum absolute angular/linear
velocity threshhold, and the amount of time they have to stay below it until
things are disabled.  My current values (for real world metrics) are

minvel = 0.100000 m/s
mintime = 2.000000s

They're pretty ruthless (but efficient) - you may want to try more
conservative values.
