[help want] the program is hangup when read my net file system

[shynome]

Describe the bug

the program is hangup when read my net file system (like bash /dev/tcp/127.0.0.1/0)

To Reproduce

// wasm guest
package main

import "github.com/shynome/go-fsnet/dev"

func init() {
	http.DefaultClient = &http.Client{Transport: dev.Transport}
}

func main() {
	go func() {
		for {
			time.Sleep(time.Second)
			log.Println("not hangup")
		}
	}()
	time.Sleep(5 * time.Second)
	addr := fmt.Sprintf("http://%s", os.Args[1])
	resp := try.To1(http.Get(addr))
	io.Copy(os.Stdout, resp.Body)
}

// host server
func TestMain(m *testing.M) {
	l = try.To1(net.Listen("tcp", "127.0.0.1:0"))
	defer l.Close()
	go http.Serve(l, http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
		log.Println("get request")
		time.Sleep(5 * time.Second)
		io.WriteString(w, word)
	}))

	m.Run()
}

Run this test you will see the log is stop when request response hangup

Additional context

#1500

I feel this is about nonblock file flag, but I don't know how to add nonblock file flag to my net file system

I found poll-method, maybe I should implement this?

[shynome]

oh the nonblock file implement function is not public now, waiting it....
