Well, this was off the top of my head, Robert. Also, I know
for a fact that you and the code crankers behind /dev/random
know infinitely more about random-number generation than I
ever will :^).

Kewl! :^). Now think up a crazy-sounding acronym to call the process.
Hmmm. Let's see if we can somehow work words like CRAP, FARTS, or DORK
into the name, too. I think it would be totally hilarious to go to a
conference and here some serious-sounding and well-meaning speaker
say something like, "The obvious solution to this type of random-
generation problem is CRAP." :^) :^). The major problem here, though,
is that the audience might be laughing too much to actually pay
attention to what was being said. They'd probably be hanging on
every word, waiting to here the term used in a context that actually
meant something else :^). Hmmm. OTOH, maybe an acronym like this would
actually make the audience pay attention and listen :^).
