go - Why does fmt.Println inside a goroutine not print a line?

Question

I have the following code:

package main

import "net"
import "fmt"
import "bufio"

func main() {
    conn, _ := net.Dial("tcp", "irc.freenode.net:6667")

    reader := bufio.NewReader(conn)
    go func() {
        str, err := reader.ReadString('
')
        if err != nil {
            // handle it
            fmt.Println(err)
        }
        fmt.Println(str)
    }()

}

If I don't have the code that reads from the buffer in a goroutine, it outputs a message like this, which is what I expect to happen:

:zelazny.freenode.net NOTICE * :*** Looking up your hostname...

However, having it inside a goroutine prints nothing.

Can someone explain why that is?
