I confirm there is no difference if the xfce-power-manager process is killed.
Closing the laptop still results in a black screen with a frozen mouse cursor visible upon laptop re-open. The only recourse from this state is a power-off reboot.
The laptop does not appear to suspend when the lid is closed as it does when the hardware "Suspend" key is pressed or the menu item "Logout-suspend" is clicked. With a lid close there is no immediate disk activity and the power light stays on rather than blinks.
