I guess my concern is that we shouldn't be mucking with other  
processes' priorities.  Theoretically, they've been tested and known  
to work at whatever level was originally configured.  Doing it the way  
you've proposed obviously doesn't cause any harm, but by providing it  
as an option, users are more likely to mess things up by thinking it's  
an approved tweakable parameter.
