[erlang-questions] Did I do it right?
Sat Oct 27 09:53:25 CEST 2012
Since no one reacted yet, I've skimmed through the code very quickly and it
looks really good - I wouldn't assume it being written by Erlang novice.
The only thing I've spotted, which is rarely done in production grade
Erlang systems is use of non-OTP servers by doing manual looping in spawned
process (although I can see it does handle all sys messages and stuff). Is
there any particular reason to not use gen_server in that case?
