Scala Databinder Dispatch Http shutdown

Question

为什么http.shutdown()不停止程序?

下面是示例:

package hello
import dispatch._, Defaults._
import scala.concurrent.Await
import scala.concurrent.duration._
object Main extends App {
    val h = host("maps.googleapis.com")
    val req = h / "maps" / "api" / "distancematrix" / "xml"
    val params = req <<? Map("origins" -> "Berlin",
                             "destinations" -> "Warsaw",
                             "language" -> "pl")
    val http = new Http
    val ratioHttp: Future[xml.Elem] =
        http(params OK as.xml.Elem)
    println(Await.result(ratioHttp, 60.seconds))
    http.shutdown()
}
