Subinterpreters and multiprocessing have basically the same speed on

It does not look like there are some advantages of subinterpreters
against multiprocessing.
Maybe I'm missing something, but the example that comes to my mind is
embedding a Python interpreter in an existing nonPython programme.
My pet one-day-in-the-future example is mutt, whose macro language is...
crude. And mutt is single threaded.
However, it is easy to envisage a monolithic multithreaded programme
which has use for Python subinterpreters to work on the larger
programme's in-memory data structures.
I haven't a real world example to hand, but that is the architectural
situation where I'd consider multiprocessing to be inappropriate or
infeasible because the target data are all in the one memory space.
