Sorry for a non-answer:
I long ago reworked ForkJoin to not use this because it was much
too slow. (Sorry, I can't easily reconstruct version using it
to check changes.) If it were improved enough to run in only
a few cycles I might start using it routinely.
If it were in-between, I might use it in a different way as
a backup strategy.
