I am not sure if this is the best way to write this or if it gains performance. I am happy to get Feedback.

Good idea! Do things have to be Send? If we don't need it, people can choose to use single threaded types.

@seanmonstar I think they have to be Send because data is moved into the ReusableBoxFuture.
Maybe i could bring back the old implementation where B: !Send?
