To the JIT team — I’m not sure who’s currently working on this, but it might be a good starting point to add JIT support. My next goal will be to make the tier-two instructions thread-safe.

I think we should start by running the tests in CI for JIT+FT current build and see what passes/fails before doing this

We disabled FT + JIT build from #133179 do you think that we have to listing the current status?
Could we separate this task into making the tier 2 interpreter thread-safe (with optimizer disabled) and the optimizer thread-safe?

This makes sense but actually the default build's JIT can't even run with the optimizer turned off! There's some segfaults when we turn off the optimizer lol.

How can I trigger this?

Run the test suite with PYTHON_UOPS_OPTIMIZE=0 env var.

Just for the record at default build:
PYTHON_UOPS_OPTIMIZE=0 ./python.exe -m test -j8

Ah never mind, it need to be transformed tier 2 code first.
