There may be potential.  In traditional Unix programming, for example,
one normally performs readdir() system calls to step through the directory,
as when examining each name in turn.  Such a "onesy" approach makes for
considerable overhead in a large directory.  Ambitious programming might
attempt to read() the whole directory in one gulp and then traverse it
in memory.  Other environments might offer similar possibilities for
improvements in efficiency.
