-// Make the current process to the daemon process.

-// NOTICE: DON NOT USE THIS FUNCTION.
-//
-// When using the daemon in Go, if your program has some goroutines, they won't
-// work. One explanation is that the daemon only fork the main goroutine, not
-// other goroutines. Furthermore, once the go program is started, all the
-// goroutines about GC will run to work; and when forking the current process,
-// all those will go away.
-//
-// Notice: The above only is the guess, but it's in fact that the goroutines
-// except the main goroutine don't work when turn the go program into a daemon.
