Adopt the `@pytest.mark.skipon_spawn_backend('subint',
reason=...)` marker (a617b521) across the suites
reproducing the `subint` GIL-contention / starvation
hang classes doc'd in `ai/conc-anal/subint_*_issue.md`.
Deats,
- Module-level `pytestmark` on full-file-hanging suites:
- `tests/test_cancellation.py`
- `tests/test_inter_peer_cancellation.py`
- `tests/test_pubsub.py`
- `tests/test_shm.py`
- Per-test decorator where only one test in the file
hangs:
- `tests/discovery/test_registrar.py
::test_stale_entry_is_deleted` — replaces the
inline `if start_method == 'subint': pytest.skip`
branch with a declarative skip.
- `tests/test_subint_cancellation.py
::test_subint_non_checkpointing_child`.
- A few per-test decorators are left commented-in-
place as breadcrumbs for later finer-grained unskips.
Also, some nearby tidying in the affected files:
- Annotate loose fixture / test params
(`pytest.FixtureRequest`, `str`, `tuple`, `bool`) in
`tests/conftest.py`, `tests/devx/conftest.py`, and
`tests/test_cancellation.py`.
- Normalize `"""..."""` → `'''...'''` docstrings per
repo convention on a few touched tests.
- Add `timeout=6` / `timeout=10` to
`@tractor_test(...)` on `test_cancel_infinite_streamer`
and `test_some_cancels_all`.
- Drop redundant `spawn_backend` param from
`test_cancel_via_SIGINT`; use `start_method` in the
`'mp' in ...` check instead.
