A very good point.  I forward this to development.

This isn't fixed in 3003.  The problem is there is no way for an
administration to set their user's hard limits.  You can set up default
soft limits, but if a user knows the ulimit command, they are free
to increase their soft limits as high as their hard limits.  

I'll post again if I hear any different story, but for now I'll take it
to the Design Board.  Oh Boy!
