Bug description:
  One of the threads in gnome-settings-deamon is polling every 4 seconds
  trying to add a watch onto a non-existent directory
  /usr/X11R6/lib/X11:

  inotify_add_watch(16, "/usr/X11R6/lib/X11", IN_MODIFY|IN_ATTRIB|IN_CLOSE_WRITE|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|IN_DELETE_SELF|IN_MOVE_SELF|IN_UNMOUNT|IN_ONLYDIR) = -1 ENOENT (No such file or directory)
  poll([{fd=17, events=POLLIN}, {fd=16, events=POLLIN}], 2, 3999) = 0 (Timeout)
  inotify_add_watch(16, "/usr/X11R6/lib/X11", IN_MODIFY|IN_ATTRIB|IN_CLOSE_WRITE|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|IN_DELETE_SELF|IN_MOVE_SELF|IN_UNMOUNT|IN_ONLYDIR) = -1 ENOENT (No such file or directory)
  poll([{fd=17, events=POLLIN}, {fd=16, events=POLLIN}], 2, 3996) = 0 (Timeout)
  inotify_add_watch(16, "/usr/X11R6/lib/X11", IN_MODIFY|IN_ATTRIB|IN_CLOSE_WRITE|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|IN_DELETE_SELF|IN_MOVE_SELF|IN_UNMOUNT|IN_ONLYDIR) = -1 ENOENT (No such file or directory)
  poll([{fd=17, events=POLLIN}, {fd=16, events=POLLIN}], 2, 3999) = 0 (Timeout)

  poll([{fd=17, events=POLLIN}, {fd=16, events=POLLIN}], 2, 3998) = 0 (Timeout)
  inotify_add_watch(16, "/usr/X11R6/lib/X11", IN_MODIFY|IN_ATTRIB|IN_CLOSE_WRITE|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|IN_DELETE_SELF|IN_MOVE_SELF|IN_UNMOUNT|IN_ONLYDIR) = -1 ENOENT (No such file or directory)

  is that intentional, or a bug?  As it stands, it's causing some
  wakeups that seem unnecessary and this is keeping the system from deep
  C state idle, which is wasting power.
