Thanks,

I will not ask you why you implement your own gen_server :-)

One note, the spec. says that you also must implement the function:
system_code_change(Misc, OldVsn, Module, Extra) -> {ok, NMisc} | Error.
Neither tcp_serv.erl or the example in the spec. implements it so is this not
really necessary? I guess that if I write code for own use and know that it 
will not be updated on a running system thats ok, but for generic libraries ?
