Comment (by pbruin):
The old example would be more than twice as fast with Simon's default
parameters:
{{{
sage: %timeit -n 1 -r 1 E.rank(lim1=2,lim3=4,limtriv=2)
1 loops, best of 1: 1min 42s per loop
}}}
So indeed fixing #9322 would help.
Another thing: `E.torsion_subgroup()` fails as well, I've opened ticket
#16011 for it.
