The newest gcc emmits this warning:
```
/Modules/_tkinter.c:272:9: warning: this ‘if’ clause does not guard... [-Wmisleading-indentation]
272 | if(tcl_lock)PyThread_acquire_lock(tcl_lock, 1); tcl_tstate = tstate; }
| ^~
/Modules/_tkinter.c:2869:5: note: in expansion of macro ‘LEAVE_PYTHON’
2869 | LEAVE_PYTHON
| ^~~~~~~~~~~~
/Modules/_tkinter.c:243:5: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘if’
243 | (*(PyThreadState**)Tcl_GetThreadData(&state_key, sizeof(PyThreadState*)))
| ^
/Modules/_tkinter.c:272:57: note: in expansion of macro ‘tcl_tstate’
272 | if(tcl_lock)PyThread_acquire_lock(tcl_lock, 1); tcl_tstate = tstate; }
| ^~~~~~~~~~
/Modules/_tkinter.c:2869:5: note: in expansion of macro ‘LEAVE_PYTHON’
2869 | LEAVE_PYTHON
```
that's because the macro packs together two statements at the same level
as the "if". The warning is misleading but is very noisy so it makes
sense to fix it.

`shutil.unpack_archive()` tries to read the whole file into memory, making no use of any kind of smaller buffer. Process crashes for really large files: I.e. archive: ~1.7G, unpacked: ~10G. Before the crash it can easily take away all available RAM on smaller systems. Had to pull the code form `zipfile.Zipfile.extractall()` to fix this

It was always meant to be released for parallelization.
This now matches the other similar code in the module.
Thanks michaelforney for noticing!

When a Thread is not joined after it has stopped, its lock may remain in the _shutdown_locks set until interpreter shutdown. If many threads are created this way, the _shutdown_locks set could therefore grow endlessly. To avoid such a situation, purge expired locks each time a new one is added or removed.

The previous example did not fully showcase the interest of using gather.
Here the example showcases "the result is an aggregate list of returned values".

The patch from [bpo-44074]() does not account for a possibly non-English locale and blindly greps for "HEAD branch" in a possibly localized text.

Added two new attributes to ``_GenericAlias``:
* ``_typevar_types``, a single type or tuple of types indicating what types are treated as a ``TypeVar``. Used for ``isinstance`` checks.
* ``_paramspec_tvars ``, a boolean flag which guards special behavior for dealing with ``ParamSpec``. Setting it to ``True`` means this class deals with ``ParamSpec``.

These are passed and called as PyCFunction, however they are defined here without the (ignored) args parameter.
This works fine in some C compilers, but fails in webassembly or anything else that has strict function pointer call type checking.
