Testcase timer

In the testcase, I create four timers and they expire at the same time, but only one is actually effective。
Comment 1 xiaoxiangjian 2017-09-13 11:44:13 UTC 
It seems that the function __start_helper_thread does not block the SIGTIMER signal, causing the timer_helper_thread thread to get abnormal when it receives multiple SIGTIMER signals at the same time
