Stupid System V Machines
Some ac's on System V machines (I've tried SGI Indigo & SGI Indy)
forget to pay attention to the ut_type field in a struct
utmp. As such, they chalk up a lot of time to non-existant processes
called LOGIN or runlevel.
TANGIBLE RESULT: The amount of total time reported by the
system's ac is really off. Often, it's several times
greater than what it should be.
SOLUTION: GNU ac always pays attention to the
ut_type record, so there's no possibility of chalking up time to
anything but user processes.
