Collect 6 months worth of articles in a directory.  Then archive the
ones older than 3 months into your archive and remove them from the
directory.  Then you wait another three months and again archive the
old messages and remove them.

Now comes the problem how to remove articles.  If you're careful, it
should be possible by removing the articles themselves plus the
overview entries plus perhaps adjusting the active file.  Another
possibility is to figure out which function F is called from
gnus-agent-expire to actually delete, then get a list of messages
archived and call that function F on those messages.

Not sure how to do it for leafnode, if you decide to use that.
