If you have a gen_server that holds the socket and use handle_info to fill the 
why can't you stop it or reload the code when using active:true?

In fact, using gen_tcp:recv is a bad idea for a "rock solid" server,
because you will not be able to stop process or reload its code.

Proper way is to inet:setops(Socket, [{active,once}]), use buffer and
use erlang:decode_packet to decode lines
