This is for testing, not for merging.

See:

https://docs.python.org/3.13/whatsnew/3.13.html#an-experimental-just-in-time-jit-compiler
https://github.com/docker-library/python/issues/947
https://github.com/docker-library/python/issues/1009
https://github.com/docker-library/python/issues/1082
https://github.com/docker-library/python/pull/1043
https://github.com/docker-library/python/pull/1044

Test it with something like:

$ docker build --pull https://github.com/docker-library/python.git#refs/pull/1045/merge:3.13/slim-trixie

Btw it seems like enabling both free-threaded mode and the JIT isn't supported currently (to the point where the configure option combination is now disallowed in 3.14.0) - and won't be until 3.15: https://github.com/python/cpython/issues/133171

(So you have to do one or the other)
