ws_netpoll.go

ch := NewChannel(conn)

// Make conn to be observed by netpoll instance.
poller.Start(conn, netpoll.EventRead, func() {
    // We spawn goroutine here to prevent poller wait loop
    // to become locked during receiving packet from ch.
    go Receive(ch)
})

// Receive reads a packet from conn and handles it somehow.
func (ch *Channel) Receive() {
    buf := bufio.NewReader(ch.conn)
    pkt := readPacket(buf)
    c.handle(pkt)
}

It should be go ch.Receive() right?
