How do I get hold of exceptions thrown in a Scala Future?

Question

I\'ve been working up my answer to Is there a standard Scala function for running a block with a timeout?, and have run into a problem if an exception is thrown in a Future.

Or.... you could use Akka and it would give you what you want without you having to go through hoops for it.

val f: Future[Int] = actor !!! message

Then

    f.get 

Will throw the exception that happened in the actor

    f.await.exception 

will give you an Option[Throwable]
