optional<> would be insufficient if we don't have only success/failure
but some quality indicator. We could return a result if one of the
futures returns a result with quality == "best". Otherwise, we have to
wait until all the futures involved have returned a result.

(Something like that would be useful for running several heuristic
algorithms in parallel with a suitable definition of "best")
