Yes, but ulimit doesn't help with that.  (Actually, ulimit
also reports the maximum break, and does some other things too these days.)
Let ulimit be 1M.  All that means is that no one file I create can be
bigger than that.  There is nothing to stop me creating 500 1/2Mb files!
My experience may not be typical, but I don't think I've ever had a disc
fill up on me due to a single file being too big, in every case it has
been too many smallish junk files cluttering up the place.  The only time
I've ever noticed the existence of ulimit has been when uucp has mysteriously
lost or truncated things.  In fact things like news are a good example of how
ulimit fails to help: you get thousands of small files each of which ulimit
is perfectly happy with.

If the default ulimit had been infinity (with ordinary users only being able
to decrease it), any sysadmin who wanted the present state of affairs could
have done it with one line in /etc/profile, and sites that didn't want to
know about it wouldn't have had file transfers die mysteriously.
