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".

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.

Added in bpo-41730 (GH-22186), the test apparently causes refleaks. The
test isn't worth hunting them down, so it's simply reverted.
This partially reverts commit 4a2d98a1e9.

A C function accessible by the default exception handler, but not by python code,
finds the existing name closest to the name causing a name or attribute error. For
such errors, call the default handler after capturing stderr and retrieve its message line.
