No, because the high 32-bits for i_size are overloaded to store the
directory creation acl.

In practice, you really don't want to have a directory that huge
anyway.  Iterating through it all with readdir() gets horribly slow,
and applications that try do anything with really huge directories
would be well advised to use a database, because they will get *much*
better performance that way....
