For my next trick... I wonder whether the MD5 algorithm is such

I would say that the treatment of the last block would negate this;
it is 'padded' and then hashed. I suppose you could keep the hashes
of the penultimate blocks and then compute the last blocks' hashes,
but this smacks of a lot of chicanery for not much gain.
