I now know why.  The NIST test vectors have been generated by
reencrypting the ciphertext 10000 times.  If one looks closely at the
Rijndael test program, one can find a 'for (j = 0; j < 10000; j++)'
around that actual block encryption.

I think I'll change this to use the FIPS vectors instead.  They are
not generated with this kind of loop, at least from looking at the
rijndael-test-fst.c program.  I'll make sure this corresponds to the
published FIPS vectors.
