描述

Feature or enhancement

Proposal:

The proposal is an internal implementation of the JIT and it transparent to the user.

Has this already been discussed elsewhere?

I have already discussed this feature proposal on Discourse

Links to previous discussion of this feature:

Not on Discourse, I've had extensive discussion about this with @brandtbucher and created a prototype that we benchmarked using the faster-cpython infrastructure. The full results are here: https://github.com/faster-cpython/benchmarking-public/tree/main/results/bm-20241018-3.14.0a1+-f74cd79-JIT

On macOS on Apple Silicon there is an overall 1.4% speed improvement by replacing the mprotect with pthread_jit_write_protect_np.
