[sage-devel] Severe slowdown in elliptic curve integral_points() method

Consider the file http://boxen.math.washington.edu/home/jdemeyer/integral_points.sage (based on a doctest in ell_rational_field.pyx): E = EllipticCurve([-879984,319138704]) P1 = E.point((540,1188)) P2 = E.point((576,1836)) P3 = E.point((468,3132)) P4 = E.point((612,3132)) P5 = E.point((432,4428))
