How to run code in a separate thread?

I want to spawn a thread and run code in that thread. What are the options in Scala?

Example usage would be something like this:

Thread.currentThread setName "MyThread"

val myThreadExecutor = ???

val threadNamePromise = Promise[String]

future {
  myThreadExecutor run {
    val threadName = "MySpecialThread"
    Thread.currentThread setName threadName
    threadNamePromise success threadName
  }
}

Await.result(threadNamePromise.future, Duration.Inf)

future {
  myThreadExecutor run {
    println(Thread.currentThread.getName) // MySpecialThread
  }
}

future {
  myThreadExecutor run {
    println(Thread.currentThread.getName) // MySpecialThread
  }
}

println(Thread.currentThread.getName)   // MyThread

Is there anything in the built-in Scala library that I can use?

Edit

I updated the snippet to better reflect intent
