Why one can't submit an alternative thread pool to the streams API?

Agree that it is desirable to be able to limit the level of parallelism, but that’s not the right API either. (If it were as easy as that, we would have done it already.)
(This is exactly what I meant by my earlier comment about the real estate between “parallel(“ and “)” — everyone wants to build there, and everyone thinks they know what goes there, but so far, none of the ideas proposed are very satisfying.)
