  16. def future[T](f: Future[T]): Activity[T]

    Create an activity backed by a com.twitter.util.Future.

    Create an activity backed by a com.twitter.util.Future.

    The resultant Activity is pending until the original Future is satisfied. Future success or failure corresponds to the expected Activity.Ok or Activity.Failed result.

    Closure of observations of the run Var of the resultant Activity is not propagated to the original Future. That is to say, invoking close() on observations of Activity.run will not result in the cancellation of the original Future.
