 This is a pretty interesting patch for both DragonFly and NetBSD.  I am 
 not set up to evaluate XFCE4 right now, I can only take Dave's and 
 David's recommendation that it should be applied.
 
 In any case, if this patch works as advertised, it would be a pull-up 
 candidate.  Is there somebody more equipped to test this patch?
