I'm concerned that the rename function implicitly closes the file being renamed and breaks the lock on it before doing something as drastic as renaming it.
rename is an operation on the directory, not on the file. This is why you need write access to a directory to rename a file - no access is required to the file itself (this applies to UNIX).
