gh-108951: Document how to terminate an asyncio.TaskGroup (#123837) 
We don't want to add another API, since the recipe is straightforward and rarely needed.

The advantage is that we could backport this to the earliest Python version that has taskgroups (3.11, alas in security mode already, so we'll just do 3.12 and 3.13).

gh-116720: Fix corner cases of taskgroups (#117407) 
This prevents external cancellations of a task group's parent task to
be dropped when an internal cancellation happens at the same time.
Also strengthen the semantics of uncancel() to clear self._must_cancel
when the cancellation count reaches zero.

gh-77714: Provide an async iterator version of as_completed (GH-22491) 
* as_completed returns object that is both iterator and async iterator
* Existing tests adjusted to test both the old and new style
* New test to ensure iterator can be resumed
* New test to ensure async iterator yields any passed-in Futures as-is

Revert "Fix a code snippet typo in asyncio docs (#108427)" (GH-111271) 
This reverts commit 7f31676340.

The change resulted in a tautology and should not have been made.  There
may be an opportunity for additional clarity in this section, but this
change wasn't it :)

GH-94398: TaskGroup: Fail create_task() during shutdown (GH-94400) 
Once the task group is shutting down, it should not be possible to create a new task.
Here "shutting down" means `self._aborting` is set, indicating that at least one task
has failed and we have cancelled all others.
