Comment(by SimonKing):
Working at #11900, I observe that I get a very massive regression with
#10903:
{{{
sage: %time for E in cremona_curves([11..100]): S =
E.integral_points(both_signs=False)
CPU times: user 54.17 s, sys: 0.49 s, total: 54.66 s
Wall time: 55.38 s
}}}
With sage-4.7.2.alpha2 plus #9138 (which causes some regression in other
examples), the example only takes 16.48 s, and with #11900 it reduces to
13.22 s.
I am not totally sure that #11339/#10903 are really to blame for it, but
it is at least possible.
