according to http://golang.org/ref/mem (especially the last example)

Will BenchmakTCP be guarantted to read tcpStarted = true next time?
Will server be guaranteed to Listen before client's Dial??

func BenchmarkTCP(b *testing.B) {
        done := make(chan bool, 10)

        if !tcpStarted {
                go startServer()
