If you look at
http://msdn.microsoft.com/en-us/library/ff469527.aspx and
http://msdn.microsoft.com/en-us/library/ff469288.aspx then
you get the impression that NTFS enumerates all open files
to check whether there is anything open below a directory to
be renamed. Probably pretty expensive on a busy fileserver.
