-- This is a giant hack to "listen" for applications that close. Some

-- closes. This is actually hard. We can't just listen to
-- DestroyWindow events as VBox will "destroy" windows when it
-- switches to fullscreen and back. We also can't just monitor the
-- process from the window since WindowDestroy events don't have PIDs
-- attached to them. Therefore, the hack to make this all work is to
-- make a script fire when VirtualBox (and other apps that I want to
-- control in this manner) close. This script fires a bogus
-- ClientMessage event to the root window. This event will have a
-- BITMAP atom (which should do nothing) and a "magic string" in the
-- data field that can be intercepted here. When this event is
-- registered here, close the dynamic workspaces that are empty.
