The BGE was getting the namespace dict directly from __main__ which conflicts with my recent fix to get the pickle module working which to overwrote the __main__ module on script execution. Simple fix is to have the BGE and Blender use the same method of getting namespaces. Renamed CreateGlobalDictionary() to bpy_namespace_dict_new() and moved into bpy_internal_import.c pickle still wont work in the BGE since we make a copy of __main__ namespace but for speed would rather not have to replace the __main__ module many times per second.
