socket fd leaks if dial timeout occur

[trulyliu]

req, err := http.NewRequest("POST", s.url, buffer)
if err != nil {
	return err
}
if s.auth != nil {
	req.SetBasicAuth(s.auth.Login, s.auth.Password)
}

req.Header.Add("Content-Type", "text/xml; charset=\"utf-8\"")
req.Header.Add("SOAPAction", soapAction)
req.Header.Set("User-Agent", "gowsdl/0.1")
req.Close = true

tr := &http.Transport{
	TLSClientConfig: &tls.Config{
		InsecureSkipVerify: s.tls,
	},
	Dial: (&net.Dialer{
		Timeout:   60 * time.Second,
		KeepAlive: 10 * time.Second,
	}).Dial,
	TLSHandshakeTimeout:   5 * time.Second,
	ResponseHeaderTimeout: 300 * time.Second,
	ExpectContinueTimeout: 1 * time.Second,
}

client := &http.Client{Transport: tr}
reliableClient := pester.NewExtendedClient(client)
res, err := reliableClient.Do(req)
if nil != res && nil != res.Body {
	defer res.Body.Close()
}
if err != nil {
	return err
}

If dial timeout occur, opened socket fd will leak.
sudo lsof -n -a -p $(pidof processname) |grep "can't identify protocol" |wc -l
You will see many 'can't identify protocol' socket.

I've been moving across the country and am super bogged down. I've not forgotten about this, but I don't know when I can get to it. PRs welcome!

Can this still be reproduced? I experimented with dial timeouts on ubuntu today and couldn't reproduce leaked sockets.

To my knowledge, all leaks were patched a while back.
