I take it back.  Deleting the .overview file is not a good idea.  It
makes it impossible to retrieve any old articles at all.  I've had to
recreate the group from the server to get at any old articles.

Can anybody suggest how I can read large newsgroups on systems with
small memory?  I would have thought that gnus should be able to do
this.  Does it need to keep the whole set of headers in memory?  I'm
happy to pay the price of network access in lieu of memory overload...

Thanks,
