Comment (by nickm):

 FWIW, though I don't generally object to belt-and-suspenders engineering,
 I'm not 100% sure of this approach; if we think there's any chance that
 future outputs of our PRNG can be predicted from our past PRNG outputs, we
 should probably throw away the PRNG and use a good one, right?  (Or for
 that matter, we should revise openssl to stop exposing PRNG outputs in
 that case too.)
