That's easy -- just expire them in 2 days or so, by which
time you can be sure they've been batched, even if not yet uucp'ed.

If you don't have C news expire, just right a shell script with
cd /usr/spool/news
find talk -mtime +2 -exec rm {} ';'
find alt.flame -mtime +2 -exec rm {} ';'

etc. (of course, you can optimize this with xargs etc., but
it's no big load anyway).

If you do have C news expire, you can write yourself a
version of explist (call it, say explist-extreme) with
greatly-reduced expire times. Any time space gets really
low (you can even implement this check automatically if
you want), run expire using explist-extreme.  C news expire
uses few enough cycles that running it during the day is no
bug deal (I just did it on a busy system).

P.S. check out tor.news.stats recent postings for some
wild numbers. We've shipped out 30Mb over the past 3 days...
