No, it stays pretty constant.

The output wasn't stopping at all - just scrolling by fairly quickly. 
It was speeding up and down a little but still going too fast to see 

I was looking back through some old news.daily reports from when I had 
a similar number of articles but about half the number of news groups 
(20,000 as opposed to 41,000 now) and expireover was completing within 
the hour.

Also, expireover seemed to complete quicker when I was using timecaf as 
opposed to timehash. Does that make sense, though, because I thought 
that expireover only looked at the overview database and the history 
files, not the article spool?
