golang runtime

[Sergey Platonov]

I have modified your example: just added some networking to your go app. 
I have attached the file to the letter.

Oh, I think, I haven't mentioned it before. To enable the networking in 
the QEMU you need to add the following line to the run script:
```
append_qemu_nic_args
```

For me, localhost still wasn't available, so I was connecting to a 
remote host.
