If the catalog entry editing takes some time, then why are the files copied
to the archive before that?  Given that (presumably) the file copy is
pretty fast, would it not reduce the length of time spent in the "critical
section" (an operating system reference which I hope most of you
understand) to something very small, thus reducing the amount of time for
which the files and the catalog entry are mis-matched.

Perhaps there is a good reason for the order you pick, and if so I'd be
happy if someone could enlighten me (just out of curiosity).
