There's a conflict between the desires to do more thorough testing and
avoid flaky intermittent failures.

Especially in j.u.concurrent we embrace test non-determinism, much of it
comes from the concurrency we're testing, and retrieving a random seed for
reproducibility is not worth the effort.

No one does a good job of race prevention through testing.
