I should have given more details, sorry.

I am writing both the server and the client with twisted pb.
The server (a game server) sends messages to four player clients.

Say the game server sends messages A and B to a player client. 

Is it granted that the player client always processes A first even
if the internet routes the messages differently and B arrives
