Hello Collin,

Thanks for taking a look.

Well, I have good news: the fixes to the pure Python compiler have been
accepted and committed by Neil Schemenauer in r69373.

Not a tremendous speedup but not totally insignificant either.
(I see you like Spitfire :-))

Before committing I want to know what to do with the new jump opcodes,
with respect to the alternative proposal I've made in #4715.
Ideally, I should fold the #4715 patch back into the present patch,
since I think the #4715 approach is more thought out.
