No. My stereotypical use case is say, responding to an HTTP request that involves side-effects:

    (post "/user/foo" [request]
      (update-db)
      (future (send-user-email))
      {:status 200
       :body (render-page)})

What happens if email delivery fails? What happens if this box powers off? etc. Queues don't solve all your failure scenarios here, but they're a great first step.
