I assume that p-1 factorisation is only done once, i.e., it is only done
prior to a DC if it wasn't done at the time of the first-time test.
Isn't there a case for splitting off p-1 into an entirely separate work
unit? That way machines with insufficient memory either to run stage 2 at
all, or to do so with a good chance of success, could be given pretested
exponants for first-time/DC LLs
