So what? If I want to create a gigabyte of data when I have a
megabyte ulimit, all I have to do is create 1024 1Meg files. Easy.

What you are talking about here is some kind of quota system, one
which limits the total amount of disk space allocatable by one user.
That is completely different from ulimit.

Ulimit is a safety belt, nothing more. It is of no use to system
administrators, except in that the administrator *may* have fewer
accidental file system fillups to clean up after.
