Consider adding a way to handle parallel tasks

[JohannesMoersch]

Doing task parallelism without risking unhandled exceptions is a pain and easy to do incorrectly. Some method to allow passing multiple task factories with proper exception handling would be valuable.

[JohannesMoersch]

Ideally, if you aren't going to await a task immediate, it should have a try catch internally to assure it can never throw an unhandled exception. Also, they really should all be awaited.

There is Parallel.Invoke in the .net libraries. Perhaps this could tie in with Unions for merging failure types?
