I think the right thing to do here is make all module-level globals into "cdef public" attributes, i.e. C globals with getters and setters for Python space. I'm not sure whether this would best be done by creating a custom dict or module subclass, but it would probably be cleaner and afford much more than a 1.6x speedup.
