Comment:
First, I applied the patches from #9443 and found that all doctests pass.
Then, I applied the tickets from here, and got one doctest failure:
{{{

WARNING: saturation at primes p > 100 will not be done;
points may be unsaturated at primes between 100 and index bound

So, there will be some bug hunt needed.
