Erlang does exactly the following when detaches from a terminal:

 if (start_detached) {
   int status = fork();
   if (status != 0)
     return 0;
   status = fork();
   if (status != 0)
     return 0;

   open("/dev/null", O_RDONLY);
   open("/dev/null", O_WRONLY);
   open("/dev/null", O_WRONLY);
   execv(emu, Eargsp); /* executing the main Erlang emulator */

Is this behavior incorrect?
