如下代码：当线程ReqSender抛异常退出时，主线程一并退出。Timer里的get_t方法也退出

注意：ReqSender和Timer是两个线程类。

class MyError(Exception):      print "a error"class ReqSender():    def __init__(self,ids,idb):        self.ids=ids        self.idb=idb    def assert_case(self):        if self.ids <> self.idb :            try:                raise MyError            finally:                exit(1)class Timer():    def get_t(self):        for i in range(10):            time.sleep(3)            print iif __name__ == '__main__':    rs = ReqSender(2,3)    tm = Timer()    thread.start_new_thread(tm.get_t,())    time.sleep(10)    try:        thread.start_new_thread(rs.assert_case,())    except MyError:        print "exist"        sys.exit(1)

但当代码编程assert 和get_t同属于一个线程类。当assert方法异常退出。get_t并不会退出，而是等get_t跑完，主线程才退出。。

class MyError(Exception):      print "a error"class ReqSender():    def __init__(self,ids,idb):        self.ids=ids        self.idb=idb    def assert_case(self):        if self.ids <> self.idb :            try:                raise MyError            finally:                exit(1)    def get_t(self):        for i in range(10):            time.sleep(3)            print iif __name__ == '__main__':    rs = ReqSender(2,3)    thread.start_new_thread(rm.get_t,())    time.sleep(10)    try:        thread.start_new_thread(rs.assert_case,())    except MyError:        print "exist"        sys.exit(1)

这可能是一个线程，进程退出的问题。因为我对这块不太熟悉，所以mark以下，以后回来再思考深层原因。
