More than simply accumulating errors, this particular class of problems
shows chaotic behavior (small deviations tend to produce exponentially
divergent paths -- extreme sensitivity to initial conditions -- add a
little junk each step and you have a lot of junk). Circular maps (sine
cosine, etc) qualify.
