Running the free-threaded build of CPython 3.13 with GIL:
(CPU utilization is roughly 1 core.)
Running the free-threaded build of CPython 3.13 without GIL (
PYTHON_GIL=0):(CPU is maxed out. Unlike other tests, this one fluctuates wildly.)
Running vanilla CPython 3.12:
(CPU utilization is roughly 1 core. This test could have also also been slightly faster because it was not run in Docker.)
