[erlang-questions] prim_inet:async_accept/2

[Nicolas Thauvin]

Hello,

  prim_inet:async_accept/2 looks like a very interesting function to use in  
a gen_server. However, it is not documented.
  Several examples on the Internet already use it (like  
http://www.trapexit.org/Building_a_Non-blocking_TCP_server_using_OTP_principles).

Questions are:
- Why isn't it wrapped in gen_tcp ?
- Is it safe to use it (will it be obsolete in the next release ?) ?

Cheers,
