It comes from a deep-seated belief: never impose limitations when none are

Sure, I could allocate 1 GB of swap on my 22 GB disk, but what if I wanted
to do a molecular model that needed 11 GB?  Well, I'd be SOL.

I don't understand why everybody seems to want to hardwire constants into
the filesystems when a more flexible approach doesn't need to do that.

This can be easily handled by quotas or other policy decisions.

Gentlemen, we simply -must- break out of this 20th-century unix box we've
been living in and re-evaluate how to make our beloved OS the winner in 
the 21st century!
