Replying to [comment:15 jdemeyer]:
> I get different timings, the patch always seems to help.
What I understand from your timings is that (apparently) over the larger
ring (where the modulus does not fit on 64 bits), things are slower with
the patch.
> This seems to suggest that improvements are needed in the integer
`determinant()` function.
Agreed, on another ticket?
