Repetitive jobs (put job back to queue in handler)

[alizdavoodi]

I'm trying to implement a password rotation mechanism for our app,
in the job handler, I'm trying to put the job back to queue and run in a specific interval, so when user created we'll put the password in the queue for rotation in 500 secs

_, err = con.Enqueuer.EnqueueIn("password_rotation", 500, work.Q{"Username": u.Name, "Password": randpass})

The handler it looks like this:

func sampleHandler(job *work.Job) error {

	fmt.Printf("%+v", job.Args)

	//Logic for new password

	_, err := enqueuer.EnqueueIn("password_rotation", 500, work.Q{"Username": job.ArgString("Username"), "Password": NewPassword() })

	if err != nil {
		return err
	}

	return nil
}

pool.Job("password_rotation", sampleHandler)

Is this a good idea? Do you have any suggestions?
