我应该在不再使用时明确清除非全局ConcurrentDictionary,还是GC检测到它不再使用?

这有点关联: Is ConcurrentBag cause of memory leak?

编辑: 我问的原因是,我有以下代码(此处简化):

let myMethod() =
  async {
    let myEventList = ConcurrentDictionary<myEventParams, bool>()
    use o = myEvent |> Observable.subscribe(fun e ->
            myEventList.GetOrAdd(e, true) |> ignore)
    let! res = doAsyncThingsCausingEvents()
    myEventList |> Seq.iter(fun (e,_) -> Console.WriteLine "We had " + e.ToString())
    res
  }

...事实上,当在多个线程中多次并行调用时,它会泄漏内存。
