Added more about this to TODO. Thanks!

Particularly if you could tell it that you just blew away a timecaf buffer
or a timehash directory so that it could go do cleanup right away.

In my ideal world, INN would be able to handle minor inconsistencies but
the normal state of the server would be to have all three in sync at
pretty much all times. It really bugs me that right now, CNFS expires
articles throughout the day but the overview only gets updated at night.
But that's just one more case where the whole idea of a nightly expire
just isn't what you want.

I'll be glad to see that tested, but I'll be really surprised if it beats
a hand-tuned database format in performance. There are a couple of minor
tweaks that I plan to make to the current history format to create a new
default one, and of course the current text file will become binary by
default (part of the plan is to be able to read any older history format
too, though), but I think the layout of the index and so forth is actually
