Comment:

 This seems to work. However, it could be yet more efficient if we didn't
 have to repeatedly copy and downcase the name - e.g. if we could hand
 {{{calculate()}}} a {{{Name}}} or {{{LabelSequence}}} that was already
 downcased. But that's a minor optimization, and probably out of scope for
 this ticket.

 Of much greater concern is that the {{{Name::split()}}} technique is still
 used in {{{DatabaseClient::Finder::findNSEC3()}}}, and the ticket
 description explicitly says "for db and mem backends".
