On: gh-116167: Allow disabling the GIL

[sneed_chucker]

JavaScript, at least on the Node.JS side, make plenty use of native extensions written in C++ https://nodejs.org/api/addons.html

In any case, that should be irrelevant to getting a reasonably performant JIT running. Lots of AOT and JIT compiled languages have robust FFI functionality.

The native extensions are more relevant when we talk about removing the GIL, since lots of Python code may call into non thread safe C extension code.
