Technically, it's the order that the readdir() system call returns the 
filenames.  However, I would expect that for most filesystems, they are one 
and the same.

If you could guarantee that you created the directory in such a way as to 
have the exact same names returned by readdir() in the exact same order.

It's not "random", because given the same directory, you will get the same 
list with the same missing items in the same place.  However, I'm not sure 
why you are trying to bother, when the bug has already been fixed.
