gh-143006: Fix and optimize mixed comparison of float and int (GH-143084)
...
When comparing negative non-integer float and int with the same number
of bits in the integer part, __neg__() in the int subclass returning
not an int caused an assertion error.
Now the integer is no longer negated. Also, reduced the number of
temporary created Python objects.

gh-143460: Skip infinite recusion tests for infinite stack size ( #143606 )
...
Avoid tests being killed due to OOM on Linux if a system is configured with
'ulimit -s unlimited' by skipping tests relying on infinite recursion.
While unclear if Python should support 'ulimit -s unlimited', we should at
least try to avoid failing a PGO build running tests due to an unlimited
stack size being set.

gh-143378: Fix use-after-free when BytesIO is concurrently mutated during write operations (GH-143408)
...
PyObject_GetBuffer() can execute user code (e.g. via __buffer__), which may
close or otherwise mutate a BytesIO object while write() or writelines()
is in progress. This could invalidate the internal buffer and lead to a
use-after-free.
Ensure that PyObject_GetBuffer() is called before validation checks.

doesn't mean that `PyErr_Warn` is documented)

In optimized and `-Og` builds, arguments and local variables are frequently

`PyThreadState*` pointers `_Py_tss_gilstate` and `Py_tss_tstate` to find the
interpreter frame if we can't get the frame from the
`_PyEval_EvalFrameDefault` call.
