I would like to pick something that matches what a typical Unix system
does because I think the _fancy_ solutions actually cause weird problems
like denial-of-service attacks by just trying to log in.

How do typical open source Unix's handle it? It think they slow down
prompting for a password --- but as I remember we only allow one
password attempt per connection so that is already covered.
