>
> When async operation timeout is > 0, the number of StreamRecordQueueEntry instances keeps growing.
> It can be easily reproduced with the following code:
> {code}
>   val src: DataStream[Int] = env.fromCollection((1 to Int.MaxValue).iterator)
>   
>   val asyncFunction = new AsyncFunction[Int, Int] with Serializable {
>     override def asyncInvoke(input: Int, collector: AsyncCollector[Int]): Unit = {
>       collector.collect(List(input))
>     }
>   }
>   
>   AsyncDataStream.unorderedWait(src, asyncFunction, 1, TimeUnit.MINUTES, 1).print()
> {code}
