Oops, patch version 2 was not correct: I forgot a { ... } in ceval.c. New patch fixing this issue but leaves also the LOAD_GLOBAL code unchanged : keep the goto and don't try to factorize the 3 last instructions. LOAD_GLOBAL is really critical in performance. With patch version 3, the overall overhead is +0.4% according to pybench.
