gh-117662 introduced some refleaks, or, rather, exposed some existing refleaks. The leaks are coming when test.support.os_helper is imported in a "legacy" interpreter. I've updated test.test_interpreters.utils to avoid importing os_helper, which fixes the leaks. I'll address the root cause separately.
Check `my_object_collected.wait()` in a loop to give the main thread a
chance to merge the reference count fields. Additionally, call
`my_object_collected.set()` in a background thread to avoid deadlocking
when the destructor is called asynchronously via the eval breaker
within the body of of `my_object_collected.wait()`.
TSAN erroneously reports a data race between the `_Py_atomic_compare_exchange_int`
on `tstate->state` in `tstate_try_attach()` and the non-atomic load of
`tstate->state` in `start_the_world`. The `_Py_atomic_compare_exchange_int` fails,
but TSAN erroneously treats it as a store.
Additionally, reduce the iterations for a few weakref tests that would
otherwise take a prohibitively long amount of time (> 1 hour) when TSAN
is enabled and the GIL is disabled.
Since 6258844c, paths that might not exist can be fed into pathlib's
globbing implementation, which will call `os.scandir()` / `os.lstat()` only
when strictly necessary. This allows us to drop an initial `self.is_dir()`
call, which saves a `stat()`.

rfc9110 obsoletes the earlier rfc 7231. This document also includes some
status codes that were previously only used for WebDAV and assigns more
generic names to these status codes.
ref: https://www.rfc-editor.org/rfc/rfc9110.html#name-changes-from-rfc-7231
- http.HTTPStatus.CONTENT_TOO_LARGE (413, previously
REQUEST_ENTITY_TOO_LARGE)
- http.HTTPStatus.URI_TOO_LONG (414, previously REQUEST_URI_TOO_LONG)
- http.HTTPStatus.RANGE_NOT_SATISFYABLE (416, previously
REQUEST_RANGE_NOT_SATISFYABLE)
- http.HTTPStatus.UNPROCESSABLE_CONTENT (422, previously
UNPROCESSABLE_ENTITY)
The new constants are added to http.HTTPStatus and the old constant names are
preserved for backwards compatibility.
References in documentation to the obsoleted rfc 7231 are updated
I think the choice of wording in these docs is great and doesn't
need to change. However, it could be useful to explicitly define
this term / the cost of doing so seems relatively low.
Guido pointed out to me that some details about the per-interpreter state for the builtin types aren't especially clear. I'm addressing that by:
* adding a comment explaining that state
* adding some asserts to point out the relationship between each index and the interp/global runtime state
Replace use of `os.listdir()` with `os.scandir()`. Forgo setting `_drv`,
`_root` and `_tail_cached`, as these usually aren't needed. Use
`os.DirEntry.path` to set `_str`.
Don't bother calling `os.scandir()` to scan for literal pattern segments,
like `foo` in `foo/*.py`. Instead, append the segment(s) as-is and call
through to the next selector with `exists=False`, which signals that the
path might not exist. Subsequent selectors will call `os.scandir()` or
`os.lstat()` to filter out missing paths as needed.
