CRUSH always reduces by 128 bit, but by changing the
amount of WHIP calls before a CRUSH, we shuffle things
around a bit more.

This matches the random skips we currently use in arc4random.

Not if using this as RNG, postprocessing output from something
with 8192 bit of internal state, and more-or-less continuously
feeding input into it. In this case, the “key” is much larger
than the state.

<igli> just about the worst way you could do something like that, afaic.
<igli> it's like anti-design.  <mirabilos> that too… may I quote you on that?
<igli> sure, tho i doubt anyone will listen ;)
