  4. def acquire[X](permitCount: Long)(task: ⇒ Future[X])(implicit ec: ExecutionContext): DeferredFuture[X]

    task

    the task to run once permits are available

    returns

    a future that completes once permitCount permits are available AND task completes. task is started once permitCount permits are available. The permits are removed from the pool while task is running and after task completes the permits are returned to the pool.
