Goroutine leak or never stop

[Petelin]

i am new with hystrix, but shouldn't have a hard timeout limit? i read the code, when time is up it just return timeout err, but the real job is running in another goroutine and may be never be stoped. am i right with this?should it be solve?

	hystrix.Go("test_name", func() error {
		for{
			log.Println("hello hystrix")
			time.Sleep(time.Microsecond * 100)
		}
		return errors.New("test return err")
	}, func(e error) error {
		log.Println("ops~ got err!", e)
		return errors.New("second error")
	})

i seems we should do this by ourself. there is no safe way to close a goroutine.
