- fork the left child (or prefix) and compute with the right (or remaining).
This works better for spliterators that are right balanced such as
an iterator from a spliterator, a spliterator from a ConcurrentLinkedQueue,
a spliterator from a Node that can mirror the tree of a source spliterator.
- for AbstractTask compute right children in a loop rather than recursively to avoid
potential stack overflows for right-balanced (or degenerate) trees.

- fix forEachUtil test to avoid potential resource issues such as OOME and
non-termination.
