I'm not keen on this solution for the premise you've given.
I don't believe that when using MAM correctly you would ever end up
with "holes at unknown locations" in your local archive. I don't think
that encouraging people to use a "bisection algorithm" is the right
thing to do.
If this is a problem you are facing, let's go back to the basics and
figure out how you end up with holes at unknown locations in your
archive. And we can fix that.
