The Rijndael code makes a 2-orders-of-magnitude difference to the speed
of the Davies-Meyer hash in hash.c.
In order for the random kthread to show me numbers (I got paranoid
when it didn't seem to show up), I slowed it down by looping the
hashing "guts" 100 times :).
This very clearly shows the superior key agility of Rijndael over
Blowfish.
Now kern.random.sys.burst is still available for those very slow,
very high interrupt cases.
