For a variety of reasons, I'd like to be able to manage subinterpreters from Python code.  An initial effort would add a _interpreters module to the stdlib that exposes the basic functionality of the corresponding C-API.

A naming suggestion: let's leave the `interpreters` & `_interpreters` names free for a possible future PEP to make this a public API with a fallback multiprocessing backed implementation for implementations that don't have native subinterpreter support.

Then for this "testing and experimentation only" API, we'd go with "_subinterpreters" to match the name typically used to refer to the CPython feature.

FYI, I'm working on a low-level patch for use in the test suite for 3.7.  See issue #32604.
