Thanks for these numbers. Do you know how much of this increase is due  
co-allocating Use arrays with their users, and how much is due to the
actual shrinking of the size of Use?

Using less memory is great, though the approach used by use-diet to
eliminate the User field makes the code significantly more complicated,
so I'm looking forward to some nice comforting data on what the
savings is :-).
