Comment (by cremona):
OK, I am working on it. On your second point I am not sure that it is so
wasteful to find all roots of a polynomial in a real / complex field than
to refine one approximate root to higher precision, but I will experiment
to see if that is possible. And of course, this code (mostly by me) has
been in Sage for a few years already, all I did here was to move it!
