The rnews.c I posted does progressive expires based on disk space.  It 
does keep the disk very close to being full without ever getting 
full.  It's for C News and so it does allow the flexible per group 
specification for expiration time.  

The things I'd like to see are greater efficiency (a one pass system) 
and more smarts about what groups are being read.
