fix lost file

When I try to run the following sequece of commands. fileA is lost.

sync source is “/top”
$ cp bigfile /top/dirA/ &
$ mv /top/dirA/fileA /top/dirA/fileB
$ touch /top/dirA
$ cp fileC /top/dirA/fileA

If the higher directory’s attribute is changed, delete delay is not replaced by create delay.
