xidle(1) and autosuspend

Since my other computer is a datacenter, and my laptop is just a
glorified vt100, I figured how to autosuspend it when it's idle for some
time.

I already at xidle(1) in my .xsession to start xlock(1). I then
discovered -startCmd in xlock(1).

I know have this:

$ cat xlock_zzz
#! /bin/sh

exec /usr/X11R6/bin/xlock -startCmd "/bin/sleep 300 && /usr/sbin/zzz"

and this in my .xsession:

xidle -program /home/florian/bin/xlock_zzz -timeout 300 &

So after 5 minutes xidle starts xlock and 5 minutes after that my laptop
autosuspends. If I unlock the laptop before 5 minutes expire the sleep
gets killed and the laptop doesn't suspend.
