Consider, this doesn't really cost you much.  Seek time in a directory of
thousands of files is still tiny compared to tape behavior.

I probably wouldn't go as low as 5G, but 10G (much less than the average size
of my 3590 vols) seems pretty reasonable to me.  20G is getting big, from my
perspective.

I like this, too.
