Comment(by SimonKing):
It depends on what you call "the" leak.
At least, the patch fixes ''one'' leak, namely the one that is doctested
against. I am not sure whether it is enough to fix the leak exposed in the
ticket description:
{{{
sage: K = GF(1<<55,'t')
sage: a = K.random_element()
sage: get_memory_usage()
872.26171875
sage: while 1:
....: E = EllipticCurve(j=a)
....: P = E.random_point()
....: Q = 2*P;
....: print get_memory_usage()
}}}
The memory usage does climb, but it climbs a lot slower than, for example,
in sage-4.6.2.
