Best storage method for reader box

CNFS, as a self-expiring storage mechanism, is great for a reader box
when you have sufficient disk, or a limited active file to avoid premature 
over-writing, or a tolerance for varied retention. 

We use it with tradindexed overviews on one of our reader boxes, and it
works fine, *IF* we pass expireover -N -z /dev/null

If we just invoke expireover w/o any arguments, we see accretion of 
overview data until the partition fills (this is with groupbaseexpiry: true)
