For the curious: there are two lounges at KMG, both of which are shared by all of the airlines. I only went to one, but checked out the other and they seemed similar.
No wireless, 2 ancient computers, drink selection of water and a few sodas and tea, two packaged snacks. Interior actually wasn't too bad, especially considering the fact that people were sitting on the floor outside!
Only bad thing about KMG was that there is only one restaurant post-security. I went back out and went to a different one and had the worst meal of my life. So bad that I ended up at the KFC instead.
