err.Error() never contains "closed"

netpoll/netpoll_server.go

Lines 93 to 101 in 6a5a4f7

	// accept socket
	conn, err := s.ln.Accept()
	if err != nil {
	// shut down
	if strings.Contains(err.Error(), "closed") {
	s.operator.Control(PollDetach)
	s.onQuit(err)
	return err
	}

syscall.Accept returns Errno

And error descriptions are defined in zerros_*_*.go

cd /usr/local/go/src/syscall
grep closed zerrors_*

output no lines.
