Hmm. This must be done correctly; otherwise the PRNG can introduce
structure into the output stream. Remember that an RNG conditioning
algorithm,
unlike a PRNG, does *not* appear random by itself, and will never fool a
random-test,
whereas a PRNG may. Because the PRNG can hide a RNG failure, this might
be a bad idea.
