D'oh! Not really -- I just figured out what `mn_to_cdr' must mean.
Still, it's noteworthy that to achieve O(1)ness you had to write in
linear style not procedural style -- the variable `pair_key' in
particular -- and that you had free two references in a loop rather
than unprotecting a frame just once, outside the loop.
