Do not run on Windows

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Do not run on Windows
2. fcntl is available on Windows.

To be able to run on Windows I replaced the
get_ip_address(ifname) method with


def get_ip_address(ifname):
  return socket.gethostbyname(socket.gethostname())

This has the limitation to be used when only having one network interface.
