+* Usage 3: loop in the cycle method.
+*       user can use loop code in the cycle method, @see SrsForwarder
+*       1. create SrsThread field, with or without joinable is ok.
+*       2. loop code in cycle method, check the can_loop() for thread to quit.
+*       for example:
+*           class SrsForwarder : public ISrsThreadHandler {

+* @remark why should check can_loop() in cycle method?
+*       when thread interrupt, the socket maybe not got EINT,

+* @remark why should use stop_loop() to terminate thread in itself?
+*       in the thread itself, that is the cycle method,
+*       if itself want to terminate the thread, should never use stop(),
+*       but use stop_loop() to set the loop to false and terminate normally.
+* 
+* @remark when should set the interval_us, and when not?
+*       the cycle will invoke util cannot loop, eventhough the return code of cycle is error,
+*       so the interval_us used to sleep for each cycle.
