Fix #5 ; Ported from [Constantine threadpool](https://github.com/mratsim/constantine/tree/master/constantine/threadpool) Changes: - Implement event count backoff from Constantine - Fallback to generic futexes. [Constantine errors out instead](https://github.com/mratsim/constantine/blob/ea8c268603a5c5f5be479dda9ba27dcbdc51dade/constantine/threadpool/primitives/futexes.nim#L18). - Removed `foreignThreadsParked` redundant logic to match constantine. - Additional fixes: - https://github.com/mratsim/constantine/pull/623 - https://github.com/mratsim/constantine/pull/624 - https://github.com/mratsim/constantine/pull/625 In the fib bench, this is ~10x faster. In the SPC it's ~5x faster when setting task granularity to 1. It's 2x faster in nqueens and heat. It also does not run into the event notifier race conditions reproduced by `tests/stress/test_shutdown.nim` that cause a hang.
