gh-127266: avoid data races when updating type slots (gh-133177)
In the free-threaded build, avoid data races caused by updating type
slots or type flags after the type was initially created.  For those
(typically rare) cases, use the stop-the-world mechanism.  Remove the
use of atomics when reading or writing type flags.

This directory contains a number of Python programs that are useful
while building or extending Python.

                contain build artifacts and intermediate files.

buildbot        Batchfiles for running on Windows buildbot workers.

c-analyzer      Tools to check no new global variables have been added.

cases_generator Tooling to generate interpreters.

clinic          A preprocessor for CPython C files in order to automate
                the boilerplate involved with writing argument parsing
                code for "builtins".

freeze          Create a stand-alone executable from a Python program.

gdb             Python code to be run inside gdb, to make it easier to
                debug Python itself (by David Malcolm).

i18n            Tools for internationalization. pygettext.py
                parses Python source code and generates .pot files,
                and msgfmt.py generates a binary message catalog
                from a catalog in text format.

scripts         A number of useful single-file programs, e.g. run_tests.py
                which runs the Python test suite.
