What I'm aiming for is sort of a "permanent" disk cache/mirror that
adds records as needed.  The main issue is that the database (PubMed)
requests that we limit requests to once every three seconds.  I often
need to access data for hundreds of records, so I've set up a cron job
to cache the needed records to disk overnight.  I was using shelve
before, but the size of the file grew to about 500 mB and I started
having issues with shelve performance.  So, I just stopped using
shelve and am storing each record separately on disk now.

Thanks!
