Of course, doing so just turns it from "Running code as X gives you 
root" to "Running code as X gives you root the moment someone types in a 
root password, even if they're on a different terminal". I accept that 
this is a barrier, but the only real solution is to have each X session 
run as a different user - and that requires Linux to gain revoke() 
support.
