generates a blank pid file on Mac (Darwin)

package main

import (
	"fmt"
	"github.com/sevlyar/go-daemon"
	"html"
	"log"
	"net/http"
	"os"
)

// To terminate the daemon use:
//  kill `cat pid`
func main()  {

	fmt.Println(os.Args[1])
	if os.Args[1] == "test" {
		test("hello,world")
	}
	if os.Args[1] == "hello" {
		serveHttp()
	}

}

func test(t string) {
	cntxt := &daemon.Context{
		PidFileName: "pid",
		PidFilePerm: 0644,
		LogFileName: "log",
		LogFilePerm: 0640,
		WorkDir:     "./test2/",
		Umask:       027,
		Args:        []string{"[go-daemon sample]", "hello"},
	}

	d, err := cntxt.Reborn()
	if err != nil {
		log.Fatal("Unable to run: ", err)
	}
	if d != nil {
		return
	}
	defer cntxt.Release()

	log.Print("- - - - - - - - - - - - - - -")
	log.Print("daemon started")

	log.Print(t)
}

func serveHttp() {

	log.Print("testing!")
	http.HandleFunc("/", httpHandler)
	http.ListenAndServe("127.0.0.1:3080", nil)
}

func httpHandler(w http.ResponseWriter, r *http.Request) {
	log.Printf("request from %s: %s %q", r.RemoteAddr, r.Method, r.URL)
	fmt.Fprintf(w, "go-daemon: %q", html.EscapeString(r.URL.Path))
}

it just saves a blank PID file...Nope..Nothing on it...No PIDs
