That's the problem. P-1 factoring is different from other testing. It has to all be done in one stage. It doesn't have save&resume files like a Lucas-Lehmer test, or normal factoring. And the P-1 test doesn't determine primality, it's a method trial factoring done to reduce the number of long primality tests we have to do.
