That would work. It would also cover the case where a new release
happens while the mirroring is in progress.

On the other hand, it's difficult to advise what to do if you find that
the simple page does *not* match the most recent hashsum. You'ld have to
wait a little bit, and hope that the CDN will eventually provide the
current version.

Indeed, with the same limitation as above: if you find that the CDN
gives the old version, you'll have to wait (or bypass the CDN).
