is this filesystem-dependant?  ie:  does this assume the fs is using some
O(n) algorithm for directories (some, like XFS on IRIX and newer fs's for
linux like Reiserfs (i believe) use BTrees for directories giving them
O(logn) behavior, which should mean massively larger numbers of files in a
directory without a performance hit). maybe i'm misunderstanding the point
of the change, though.
