Notably this is used by gnome-power-manager when resuming from a suspend
state, yes? 

For example, the user opens the laptop lid (and is careful not to hit
the keyboard or mouse), g-p-m gets notified and pokes the screensaver
and either the session comes back (if lock is disabled) or the unlock
dialog is shown. Without the poke this probably wouldn't happen.
