It would seem to be writing the history file every 10 articles if you use
ACT_READ option. I don't know if it writes all of it or just the modified
parts. You can tune innd to write less often, but it doesn't seem to help
much. We are in big trouble soon if the NNTP protocol isn't quickly
revised, and we probably need a fully rewritten news system in less than a
year...
