one word of caution about linux timers:since checking for timer functions is always done by deferrable functions that be executed a long timer
after they have been activaed ,the kernel cannot ensure that timer functions will start right at their or after with a delay of up to a few hundreds
of milliseconds.所以timers不能用于那些时间要求严格的实时程序。
