The beauties of our Futures and Promises :)

True - it does. But, note again, this is just a fallback `TaskSupport` in case a fork/join pool is not being used. I am hesitant to reimplement a special `TaskSupport` for thread pool executors, given that we invested a lot of time into a different, better data-parallel scheduler that should eventually replace these (and that can work with any kind of a backing thread pool).
