+%%
+%% 1) the module name is gen_server2
+%%
+%% 2) more efficient handling of selective receives in callbacks
+%% gen_server2 processes drain their message queue into an internal
+%% buffer before invoking any callback module functions. Messages are
+%% dequeued from the buffer for processing. Thus the effective message
+%% queue of a gen_server2 process is the concatenation of the internal
+%% buffer and the real message queue.
+%% As a result of the draining, any selective receive invoked inside a
+%% callback is less likely to have to scan a large message queue.
+%%
+%% 3) gen_server2:cast is guaranteed to be order-preserving
+%% The original code could reorder messages when communicating with a
+%% process on a remote node that was not currently connected.

+%%% The idea behind THIS server is that the user module
+%%% provides (different) functions to handle different
+%%% kind of inputs. 
+%%% If the Parent process terminates the Module:terminate/2
+%%% function is called.
+%%%
+%%% The user module should export:
+%%%
+%%%   init(Args)  
+%%%     ==> {ok, State}
+%%%         {ok, State, Timeout}
+%%%         ignore

+%%%
+%%%   handle_call(Msg, {From, Tag}, State)
+%%%
+%%%    ==> {reply, Reply, State}
+%%%        {reply, Reply, State, Timeout}
+%%%        {noreply, State}
+%%%        {noreply, State, Timeout}
+%%%        {stop, Reason, Reply, State}  
+%%%              Reason = normal | shutdown | Term terminate(State) is called

+%%%        {stop, Reason, State} 
+%%%              Reason = normal | shutdown | Term terminate(State) is called
+%%%
+%%%   handle_info(Info, State) Info is e.g. {'EXIT', P, R}, {nodedown, N}, ...
+%%%
+%%%    ==> {noreply, State}
+%%%        {noreply, State, Timeout}
+%%%        {stop, Reason, State} 
+%%%              Reason = normal | shutdown | Term, terminate(State) is called
