I dunno; that's merely what I was taught in the early Unix days and it got 
ingrained into me.

Nowadays I just issue "shutdown -[r|h] now" (I'm the only user)...

More Unix lore: sleep(1) could return straight away at one time (the 
granularity was 1 second).

-- Dave, who remembers when sleep(3) used to be sleep(2)
