/* [d20210220]
* 沒人參考它時, 有機率被釋放
* 但其參考的 Task, 其實還沒完工
* 1. 若此 Task 只是沒人參考, 不應強制Dispose
* 2. 若此 Task 是應用程式結束時, 應被強制關閉
* 原生Task選擇不關閉, 應自主結束
* 但這邊考量的是應正確釋放資源
*
* 或許原生才是對的, 你不應強制關閉Task,
* (1) 該Task要有自主判斷停止的功能,
* (2) 應用程式強制關閉時, 其實Task也會被關閉
* 所以, 若你要用一個不受控的Task, 那不如用原生的
*
*
* 結論: 其實原生Task 你也沒辦法強制關閉它, 你也只能直接Try/Catch起來
* [d20211230] 最好是 應用的代碼 可以確保在一段時間內可以進入下個迴圈
