gh-143706: Fix sys.argv not set during multiprocessing forkserver __main__ preload ( #143717 )
...
The forkserver was not passing sys.argv to its main() function, causing
sys.argv to be empty during `__main__` module import in child processes. This
fixes a non-obvious regression inadvertently introduced by the gh-126631 main
preloading fix.

gh-140795: Remove 'exc' field in SSLObject (gh-143491)
...
The 'exc' field was used by our debug SSL callbacks. Keep the exception
in the normal per-thread state to avoid shared mutable state between
threads.
This also avoids a reference count leak if the Python callback raised an
exception because it can be called multiple times per SSL operation.

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.

PyObject_GetBuffer() can execute user code (e.g. via __buffer__), which may
close or otherwise mutate a BytesIO object while write() or writelines()

Ensure that PyObject_GetBuffer() is called before validation checks.
