This is the part of what we did in Shenandoah to exploit parallelism during safepoint cleanups:
You'll probably get better results if you can reuse GC worker threads to do the safepoint cleanups,
but that requires GC workers to be suspendable for non-GC safepoints. Having a separate thread pool
is fine for now: Shenandoah does the separate thread pool, the proposed ZGC code also does it.
