    Oops, make that:

	next_index += PQ_L2_SIZE/4;
	if (next_index > PQ_L2_MASK)
		next_index = (next_index + PQ_PRIME1) & PQ_L2_MASK;

    Or even just:

	next_index = (next_index + PQ_PRIME1) & PQ_L2_MASK;

    Both seem to work pretty well w/ lmbench, though nothing really sticks
    its nose out.
