Thank you for your answer.

If I understand correctly,
POSIX behavior should be able to replace the writable opened file by rename().
But, It does not work on my Cygwin environment.

Is it no problem if Cygwin's behavior is different from POSIX behavior?
If so, we need different application handling for Cygwin and POSIX.
