FWIW, the function now runs much faster after the multiple precision
improvements. The worst case is only about a 100 times slower now instead of
1000 times.
I've not looked yet, but I think there is a case for capping maximum precision
for worst case computation for sin (and all trigonometric functions) as well,
so this could get even better.
