The process above will rebuild the directory *and* copy all the content
- with possible effects on the disk layout for entries within that
directory etc.

Whats the effect of instead doing:-
	mkdir new
	mv old/* new/
	rmdir new

which will sort/compress the directory but not affect the content (or
alternatively you could ln all the files into place - which might be
less confusing for anything looking at those directories at the time).
