deadline causes instant disconnection

[matjam]

Setting the deadline here:

telnet/connection.go

Line 207 in d54e7db

c.SetReadDeadline(time.Now().Add(time.Microsecond))

Seems to cause issues if you try to do something like this:

func telnetHandler(c *telnet.Connection) {
	log.Printf("Connection received: %s", c.RemoteAddr())
	c.Write([]byte("Connected!\r\n"))

	var b []byte = make([]byte, 1)
	for {
		log.Println("reading a byte")
		_, err := c.Read(b)
		if err != nil {
			log.Error("error reading from telnet client: ", err)
			log.Error("closing socket")
			return
		}
		log.Println("character received: ", string(b))
	}
}

For my application, I need to read 1 character at a time and the deadline code seems to time out the Read(). Removing the deadline resolves the issue for me.
