I should note that the use of "Continuously Seeded" is due to Hugo Krawczyk,
who pointed out that "Cryptographically Strong" isn't really appropriate since
we don't have any provably cryptographically strong generators (well, you can
argue about BBS I guess...), while "Continuously Seeded" more closely reflects
the way it works.
