Comment:
Problem was that exponent was a `cdef unsigned long`, which doesn't
necessarily fit in a python int, so apparently cython converts that to a
python long automatically.
By defining it to be a `cdef long` instead I don't think we'll get any
overflow (it's an exponent of a prime in the factorization of an integer!)
and now the exponent is returned as a `python int` instead. Unless people
feel strongly that this should be cast to a `Integer` instead, I think
this should be sufficient.
