how to time out a scala future

	val realFuture = Future(doRealStuff())
	//timeoutFuture does a spin wait by sleeping on the thread on which it runs, so make sure the ExecutionContext
	//on which it runs is multi-threaded. In an akka based environment, use a scheduler to fulfill a promise with a failure
	//when the timeout duration is complete, and avoid the spin wait
	val timeoutFuture = Future {
	Thread.sleep(timeoutMilliseconds)
	throw new TimeoutException("timeout")
	}
	Future.firstCompletedOf(realFuture :: timeoutFuture :: Nil)
