the Men & Mice Unbound team (with great help from Wouter and Olaf from
NLNetLabs) has compiled an article that explains the inner workings of
the Unbound requestlist. The article gives background information on how
the implementation of the request-list enables Unbound to survive in
Denial of Service (DoS) attacks while still serving good client
requests.  The details of the request-list helps understanding the
configuration options available for sizing this list, and explain some
of the statistics counter.
