IIRC, the last status was that even after this PEP, Py3 still has serious
issues with keeping extension modules in separate interpreters. And this
probably isn't worth doing anything about because it won't work without a
major effort in all sorts of places. And I never heard that any extension
module even tried to support this.

I don't think we should invest too much thought into this direction.
