Comment (by jdemeyer):
Just a question (not something to do for this ticket): did you ever
consider computing the CM discriminant using the period lattice? If you
have a sufficiently good (I guess this is the hard part) approximation to
τ, you can compute its minimal polynomial A τ^2^ + B τ + C and from that
the discriminant.
