Yes. you're right, this is meant to be a temporary solution only (that's
why I didn't close the bug report yet). The proper solution would be
either to use a bignum library or avoid counting the geodesics
explicitly (since we only need a ratio of two geodesic counts in the
end). We will have to think about it, though.
