[erlang-questions] prim_inet:async_accept/2

Why not use plain gen_tcp:accept() and then gen_server:enter_loop() ?

With an accept timout you can fall out and poll for mailbox messages and get
back into trying to accept again, making it semi-active.

About prim_inet being safe to use, what I have picked up pretty clearly from
OTP is that if-it-isnt-documented-it-should-not-be-depended-on.
