Comment (by SimonKing):
I have slightly updated the patch. Only difference: A dictionary, that
previously was declared as "cdef object", is now "cdef dict".
I repeated timings for `sage -t devel/sage/sage/schemes/elliptic_curves/`.
I did three runs, the time is in seconds:
__Vanilla sage-5.2.rc0__
442.5, 441.9, 442.3
__sage-5.2.rc0 plus the patch__
443.3, 440.8, 442.1
So, apparently the 2.3% regression that I found earlier has been random
noise.
