If I have understood correctly, xfce4-session nowadays waits until xflock4
finishes, before it suspends. The problem was especially with xscreensaver,
since it can be configured to fade screen given time and it may slow anyway
[1]. However, since current xflock4 runs 'xscreensaver-command -lock' in
foreground, it waits until the fading is complete.
