It would be nice, especially for a news server running INN
(hmm... this seems to be a pretty good pathological worst
case lately), to shrink the directory, say, if the contents
warrant a significantly smaller directory. This would keep
the number of huge (and slow) directories down, considering that
a lot of groups get occasional very large floods.
