[issue35420] how to migrate a c-extension module to one that supports subinerpreters?

Hi (and sorry for the delay -- it's a busy time of year).

Unfortunately, there's no good documentation yet. Python's standard library 
itself is not free of global state, and I don't think we want to start 
documenting before that's fixed.

New submission from mattip :

NumPy does not currently support subinterpreters, it has global state that is 
not cleaned up when releasing the module. I could not find a description of the 
steps I need to take to modernize the C-extension module to be able to used 
under a subinterpreter. It would be nice to describe this in the Python 
documentation, or does such documentation exist?
