celery-celery-10086
During a race in asynchronous pool cold shutdown, cleanup may receive a process object that does not have a `_sentinel_poll` attribute, or whose sentinel poll has already been cleared. This can cause shutdown to fail with an `AttributeError` instead of completing normally.
Cleanup should safely handle processes without an active sentinel poll and leave the event hub unchanged in that case. When a process does have an active sentinel poll, cleanup should remove it from the hub and clear the process’s stored sentinel state.

It directly reads `proc._sentinel_poll`, unlike tracking which already tolerates a missing attribute. The intended behavior maps directly to using `getattr(proc, '_sentinel_poll', None)`: return without touching the hub for absent/`None`; for an active descriptor, remove it, close it, and reset the stored state. I’ll first reproduce the current `AttributeError` with a minimal fake process/hub, then apply this focused change.

The reproducer now completes for both missing and explicitly cleared sentinel state without calling the hub. The active-path semantics remain intact, including clearing the process state before hub removal/descriptor close. Targeted concurrency and worker tests pass (73 passed, 1 skipped). I’ll perform the final diff/checklist review now.

AttributeError 'Proc' object has no attribute '_sentinel_poll'
The failing path is `AsynPool._untrack_child_process`: it directly reads `proc._sentinel_poll`, unlike tracking which already tolerates the attribute being absent. I reproduced the reported `AttributeError` with a process-like object lacking that attribute. I’ll make untracking use a missing-safe lookup; the existing active-state branch already removes the hub registration, closes the duplicated descriptor, and clears the stored state.

The focused pool test passes. I also verified the active case: the hub receives the sentinel fd, the process state becomes `None`, and the fd is closed. `git diff --check` is clean, and only the intended source file changed. The fix is general for both absent and explicitly cleared sentinel state, while preserving existing active cleanup behavior.

The focused reproducer now passes all three cases: absent sentinel state is a no-op, explicit `None` is a no-op, and an active descriptor is removed and cleared. The affected asynchronous pool and worker file-descriptor tests pass. I’m doing the final diff/checklist review now.
