I'm wise as king Solomon. And in my wisdom, I proclaim: render unto the 
user the thing that is user's. May he provides the list of heads in the 
correct order:

(setf *xrandr-heads* '("HDMI1" "VGA1"))

(defun dim-inactive-head (arg1 arg2)
  (let* ((brighthead (slot-value (current-head) 'number))
         (dimhead (if (eql brighthead 0) 1 0)))
    (run-shell-command
     (format nil "/usr/bin/xrandr --output ~d --brightness 1.0" (nth 
brighthead *xrandr-heads*)))
    (run-shell-command
     (format nil "/usr/bin/xrandr --output ~d --brightness 0.7" (nth 
dimhead *xrandr-heads*)))))

That'll "fix" the problem of the stuck xrandr, too ;)
