What happens when a body does have a contact joint and it is still
following a parabolic path? For instance, a box slowly tipping over on
one corner typically auto disables while reaching it's zenith because
it's linear and angular velocity is small. If a user suspects that
they can increase the global disable velocities with this patch, this
problem would become more prevalent. No?
