1.21 Gigawatts. Remove non-future indexing loop.

Tried to have a seperate futures loop but it's too confusign having
too write a Trait2, functon2, etc version of everything and keep it together.

Futures are functional sort of, so the synchronous versioun can be removed.
It still needs a ton of work though to be ready, or even get near the perf
of of the sync+rayon version.
