  Thread thread = Thread.ofPlatform().daemon().start(runnable);

  // Create an unstarted thread with name "duke", its start() method
  // must be invoked to schedule it to execute.
  Thread thread = Thread.ofPlatform().name("duke").unstarted(runnable);

  // A ThreadFactory that creates daemon threads named "worker-0", "worker-1", ...
