It seems to me that the choice of the method name is the problem here.
It maybe would be better if there was a method
+fetch_remaining_entries+ or simply +fetch_remaining+ that returned
the remaining entries. IMHO the name Dir.entries suggests that it is
an accessor of Dir, and does not imply any change to the state of the
dir object.
