There are still some issues with the complete example in the previous section. W hen the node the user logs on to crashes, the user does not log out of the system, so the user is still in the server's User_List, but the fact is that the user is no longer in the system. T his prevents the user from logging on again because the system believes it is already in the system.
Or, if the server sends a message that fails, which can cause the client to wait in the await_result function, how do you deal with it?
