The length of a spline equals the sum of the straight sub-lengths as the
interval of evaluation approaches zero.

It also equals the integral of the equation of the spline, or the sum of the
integrals of the definable equations of the segments of the spline.

In other words, if you can figure out the equations involved you could
chop the spline up into fewer pieces and come up with an exact answer in
less time.
