Unfortunately not everything that writes file is started by a getty.
For example, many things that write log entries are started directly
by init running the rc? scripts.  Other things are started by cron.
SysV should let you fix these by putting the entries in the root
crontab as "ulimit nnnn ; su -c user command ..." but that is pretty
ugly.  Even more unfortunately, many background processes inherit their
ulimit from more or less random parents.  Suppose you send mail to
another machine and your ulimit is set low.  Mail will invoke uucico
to deliver the file.  Guess what happens if the other machine has a
huge file waiting to be picked up....
