The memory layout of PyThreadState was unintentionally changed in the recent
3.9.3 bugfix release. This leads to crashes on 32-bit systems when importing
binary extensions compiled for Python 3.9.0 - 3.9.2. This is a regression.
We will be releasing a hotfix 3.9.4 around 24 hours from now to address this
issue and restore ABI compatibility with C extensions built for Python 3.9.0 -
3.9.2.
