GIL or Global Interpreter Lock can be disabled in Python version 3.13. This is currently experimental.

Python 3.13 brings major new features compared to Python 3.12 and one of them is free-threaded mode, which disables the Global Interpreter Lock, allowing threads to run more concurrently.

The GIL will be disabled when you configure the Python with the --disable-gil option which is nothing but a build configuration (free threading build) at the time of installation.

This will allow optionally enabling and disabling GIL using the environment variable PYTHON_GIL which can be set to 1 and 0 respectively.

It will also provide a command-line option -X gil which can also be set to 0 (disable) and 1 (enable).

This is really going to change the game for certain applications!

Being able to thread Python properly is really going to help it compete with NodeJS and JVM workloads (especially if they continue to work on proper JIT for Python).
