I believe you can compile Python as a shared object (.so) on Linux as
well, and thus loadable by ctypes.

Why not?

That solution is safe. But I am looking into sharing objects. I don't
think its impossible.

PyObject* pointers can be passed around. GILs can be acquired and
released, refcounts increased and decreased, etc. but we have to sort
out some synchronization details for the shared objects. For one
thing, we have to make sure that a garbage collector does not try to
reclaim a PyObject* belonging to another interpreter. But here we are
talking about minor changes to CPython's source, or perhaps none at
all.
