                            ### 陷阱一
Ticker用于for循環時，很容易出現意想不到的資源泄露問題，下面代碼演示了一個泄露問題：
~~~go
func WrongTicker() {
    for {
        select {
        case <-time.Tick(1 * time.Second):
            log.Printf("Resource leak!")
        }
    }
}
~~~
上面代碼，select每次檢測case語句時都會創建一個定時器，for循環又會不斷地執行select語句，所以系統里會有越來越多的定時器不斷地消耗CPU資源，最終CPU會被耗盡
