As Steve noted, this is probably easy. What Cython produces is just the C code file for an extension module. Whether you turn that into a shared library or statically link it into something else (that knows how to initialise an extension module) is up to you. I would say, from the point on where CPython is ready to initialise its own extension modules, it can also initialise Cython generated modules. So, just to give an example, if you want to compile difflib.py into an accelerator module and link that into the core, that's probably fine, as long as you first initialise everything that difflib needs in its module init code (such as importlib to execute the module level imports) before you initialise the compiled difflib module.
