 * The Idea behind this is quite simple: when all managed windows are closed
 * and the WM exits, there should have been an unref call for each ref call. To
 * test do something like
 *
 * export DISPLAY=:whatever;
 * export MB_DEBUG=obj-ref,obj-unref
 * matchbox-window-manager-2-simple &
 * gedit
 * kill -TERM $(pidof gedit)
 * kill -TERM $(pidof matchbox-window-manager-2-simple)
 *
 * If you see '=== object count at exit x ===' then we either have a leak
 * (x > 0) or are unrefing a dangling pointer (x < 0).
