Extended Description

The current implementation of async boots up a new thread for every call. There are likely better implementations, which will become easier to adopt once we have better parallelism machinery.

We should look into improving std::async as part of implementing parallel algorithms.

Also we should reconsider the implementation of std::future and the rest of the stuff in

Assigning to Marshall, since your working on this.
