[Xmonad] darcs patch: use a global IORef to keep list of urgent windows

27 Oct 2007


      Somebody asked for the ability to display which workspaces had urgent windows in them in the logHook.
Well, here it is. (Well, the core state-tracking functionality.) Please provide input on:
 - If it's bug-free (no space-leaks, safe-ish unsafePerformIO, etc.)
 - If it's useful (whoever you were that asked for it)
