Many thanks for the feedback. Here's a rewritten eventHook-based
version that uses ExtensibleState:

http://hpaste.org/fastcgi/hpaste.fcgi/view?id=24464

Compiles cleanly with ghc-6.10, unfortunately I don't have 6.12 to try it there.
I wasn't aware of ExtensibleState since I was still on a 0.9.1
codebase.. nice stuff.

Docks aren't still recognized, even with getInputFocus from
Graphics.X11.Xlib.Misc instead of XMonad's W.focus

I'll send a patch to contrib once there're no pending corrections.
