> This patch makes it slow for small iterators

That is a one-off cost for the __length_hint__ of the range object specifically.
Objects with a known length (lists, sets, tuples) would not have that overhead.

I can run a more useful set of benchmarks against this.

So the +0.6us would be the same for ranges 8-16. Then less for 16-25, then again for 25-35 as the removal of the reallocation process has a more significant factor for larger ranges.
