Trying to create a listener I can pass to the worker.

gistfile1.go

func startWorker() {
  cmd := exec.Command("myworker");
  f, err := os.Create("/tmp/worker7.sock");
  if (err != nil) { panic(err); }
  _, file_err := net.FileListener(f); // ERROR: getsockopt: socket operation on non-socket
  if (file_err != nil) { panic(file_err); }

  cmd.ExtraFiles = []*os.File{ f };
}
