It does.  It does call shutdown -r now, after all.  Been doing it for years, 
never had a problem (I know, anecdotal evidence <knocks on wood> :).

Well, it does.  But what I said had to do with C-A-D and X: X doesn't 
propagate the keypresses and it steals the keyboard from the system--read
"You cannot C-A-D from X".

It doesn't check.  Neither does SysV nowadays (it was a stupid shutdown
users shell/script anyway.)
