尝试 gevent 生成 greenlet 的两种方法

        gevent.sleep(self.timeout)
        print("I'm from subclass of Greenlet and done!")


class TestMultigreen(object):

        green2 = MyGreen(self.timeout, 'just 2 test')
        green2.start()

        gevent.joinall([green0, green1, green2])
        print('Tasks done!')

    def _task(self, pid, msg):
        print("I'm task %d and want to say: %s" % (pid, msg))
        gevent.sleep(self.timeout)
        print("Task %d done." % (pid,))


if __name__ == '__main__':
    test = TestMultigreen()
    test.run()
