Suggestion to the author: try to use portalocker [1] so that the module can also work in Windows. Currently it doesn't because the code uses the fcntl module that is *nix-only.

Yes, it failed to import because of fcntl. Since you can't just replace fcntl with an equivalent win32api call, I suggest using portalocker.
I usually log on *nix servers from a Windows desktop, so ShutIt could be an useful addition to my toolbox - once it works on Windows, that is.
