People making long posts whose sessions expire

Hmm...I set my timeout really low to try this, then I hit reply and typed something but waited to time out before submitting. I got a page that said "you can't access that page for some reason, please log in" or whatever. When I typed in my user name and password on that error page, my reply was submitted. So I guess what I'm saying is I think it already does what you want.
