This works in Windows 8.. Thanks!

Thank you :) I'm using this for http://mio-lang.org/ as part of it's tab completer function

I thought about using it for some stuff I'm writing it (thanks for providing it btw),
I forked it and added some 'caching' so it does not run all the tests again over and over:
https://gist.github.com/Captank/7912710
It boosts it just a bit, 100k calls of the original get_terminal_size() took ~2.4 seconds, now it's just 1.8 seconds
(I'm not sure if that would be the pythonic way, I've just started learning python :'D)
