#11468: Memleak when using elliptic curves

Using the following piece of code makes the memory footprint of sage
[[BR]] grow indefinitely: [[BR]]
sage: K = GF(1<<50,'t') [[BR]] sage: j = K.random_element() [[BR]] sage:
while 1: [[BR]] ....: E = !EllipticCurve(j=j) [[BR]] ....: del E
[[BR]] ....: [[BR]]
This seems to be less dramatic with finite fields of char != 2 and
[[BR]]inexistant for ZZ and QQ.
However this makes big computations involving different elliptic curves
quite inpractical.[[BR]]
