Both will be disallowed in Python 3.15. To create a TypedDict class with 0 fields, either use `class TD(TypedDict): pass` or `TD = TypedDict("TD", {})`.

    Deprecate creating a typing.NamedTuple class using keyword arguments to denote the fields (`NT = NamedTuple("NT", x=int, y=str)`). This will be disallowed in Python 3.15. Use the class-based syntax or the functional syntax instead.

    Two methods of creating `NamedTuple` classes with 0 fields using the functional syntax are also deprecated, and will be disallowed in Python 3.15: `NT = NamedTuple("NT")` and `NT = NamedTuple("NT", None)`. To create a `NamedTuple` class with 0 fields, either use `class NT(NamedTuple): pass` or `NT = NamedTuple("NT", [])`.

    The syntax used in the current docs (a / before any args) is invalid.

    I think the right approach is for the arguments to arbitrary
    filter functions to be treated as positional-only, meaning that users
    can supply filter functions with any names for the argument. tarfile.py
    only calls the filter function with positional arguments.

    pythongh-105407: Remove unused imports (python#105554)

A static (process-global) str object must only have its "interned" state cleared when no longer interned in any interpreters.  They are the only ones that can be shared by interpreters so we don't have to worry about any other str objects.

We trigger clearing the state with the main interpreter, since no other interpreters may exist at that point and _PyUnicode_ClearInterned() is only called during interpreter finalization.

We do not address here the fact that a string will only be interned in the first interpreter that interns it.  In any subsequent interpreters str.state.interned is already set so _PyUnicode_InternInPlace() will skip it.  That needs to be addressed separately from fixing the crasher.

There was a slight race in _Py_ClearFileSystemEncoding() (when called from _Py_SetFileSystemEncoding()), between freeing the value and setting the variable to NULL, which occasionally caused crashes when multiple isolated interpreters were used.  (Notably, I saw at least 10 different, seemingly unrelated spooky-action-at-a-distance, ways this crashed. Yay, free threading!)  We avoid the problem by only setting the global variables with the main interpreter (i.e. runtime init).

The two tests are crashing periodically in CI and on buildbots.  I suspect the problem is in the _xxsubinterpreters module. 
 Regardless, I'm disabling the tests temporarily, to reduce the noise as we approach 3.12rc1.  I'll be investigating the crashes separately.

This fixes a crasher due to a race condition, triggered infrequently when two isolated (own GIL) subinterpreters simultaneously initialize their sys or builtins modules.  The crash happened due the combination of the "detached" thread state we were using and the "last holder" logic we use for the GIL.  It turns out it's tricky to use the same thread state for different threads.  Who could have guessed?

We solve the problem by eliminating the one object we were still sharing between interpreters.  We replace it with a low-level hashtable, using the "raw" allocator to avoid tying it to the main interpreter.

We also remove the accommodations for "detached" thread states, which were a dubious idea to start with.
