I tried Ernst's Mlucas on the DS20, and it wanted to use 384k for M38.
I'm just trying MacLucasUNIX now, and it's done 27500 iterations using a
256k FFT. At 0.077 secs/iter, it should take about 150 hours to run to
completion. I'll see if I can get permission to run the full test.
MLU seems to use a 256k FFT for 8388473 (no jump to 512k after 5000
iterations), and a 512k FFT for 8388539.
