In the general reasonable case, if you have eg. 50 entries in a directory
file that could hold 100 or maybe 150 such entries, then you might want
to keep the directory file that large to handle future traffic.
Truncating it and then adding noncontiguous blocks later is a performance
hit; searching a directory that occupies contiguous blocks is a win. The
pathological case is when you find 50 entries in a directory file that
could hold 10000; obviously you want to free up quite a few blocks there.
