The memory layout of PyThreadState was unintentionally changed in the

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.
Thanks for the hotifx.
However, I need to ask: Would this also happen if there was a rc version
of 3.9.3?
Unless the mistake was just introduced, the mistake would have happened.
One this severe would likely have been caught within the week or two
before a final. But as Łukasz noted when announcing the change, .rcs
are generally ignored. (I suspect that most everyone assumes that
someone else will test them. And begging people to not do that does not
work well enough to justify the release.) 3.8.5 (2020 July 20 was hotfix
for 3.8.4 (2020 July 14, which did have a candidate, which did not get
tested the way that 3.8.4 itself was.
