Note that subinterpreters share the GIL currently, and the objects you
can pass between interpreters will be quite restricted initially.
However, the ultimate goal is to stop sharing the GIL between
interpreters and to broaden the types that can be passed between
interpreters.  Regardless, the isolation inherent to subinterpreters
provides benefits immediately.
