In the general case, if the number of files in a directory has previously
hit some high-water mark, there's a chance it'll happen again, and having
that much contiguous space allocated to the directory should be a win.
Certainly, there may be cases of spewage causing really huge directories,
and if steps have been made to prevent that happening again it would be
useful to wind them back to a more reasonable size.
What would be useful for news servers would be an option to defrag
directories only, to thereby improve performance, and not bother with
files that are probably going to get expired soon anyway.
