This is quite off-topic for the thread, but ... we actually had an
implementation of the Wisconsin benchmark in src/test/bench, which
we eventually removed (a05a4b478). It does look like the modern
regression tests borrowed the definitions of "tenk1" and some related
tables from there, but I think it'd be a stretch to say the tests
descended from it.
