Below is the protocol in some more detail:

1. The client looks for a compatible idle daemon. If there isn't one, it starts a new daemon.
2. The client connects to the idle daemon and sends it a request to do some work. If the daemon is no longer running, the client starts again.
3. If the daemon is not able to run the request, for example it is already running a request or is shutting down, it rejects the request. The client starts again.

    yield {"msg": "hello"}
    yield {"msg": "world"}

    assert response.status_code == 200
    assert response.headers["content-type"] == "text/event-stream; charset=utf-8"

}

func saveKeyEtcd(ctx context.Context, client *etcd.Client, key string, data []byte, opts ...options) error {
	timeoutCtx, cancel := context.WithTimeout(ctx, defaultContextTimeout)
	defer cancel()
	if len(opts) > 0 {
		return saveKeyEtcdWithTTL(ctx, client, key, data, opts[0].ttl)
	}
	_, err := client.Put(timeoutCtx, key, string(data))
	etcdLogIf(ctx, err)
	return etcdErrToErr(err, client.Endpoints())
