450,000 text files, Eric? :)

Pan's footprint after starting up is 7.5 meg for me.

The footprint after loading a group wth 26,000 headers is 35 meg.

Of the added 27.5 meg, 15 of it is GTK's overhead of filling the
header pane with 25,000 nodes.

The rest of it goes to the article structs, which are threaded together.
Most of this memory is carefully measured -- for example, strings are shared
so the author's name is only in one string, rather than N duplicate strings,
one per post.

Good question.
