gh-16429 introduced support for an iterable of separators in
Stream.readuntil. Since bytes-like types are themselves iterable, this
can introduce ambiguities in deciding whether the argument is an
iterator of separators or a singleton separator. In gh-16429, only 'bytes'
was considered a singleton, but this will break code that passes other
buffer object types.
Fix it by only supporting tuples rather than arbitrary iterables.
Closes gh-117722.
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.

* remove load extension doctest since we cannot skip it conditionally
* remove sys.unraisablehook example; using unraisable hooks is not "an
improved debug experience"
Replace tri-state `follow_symlinks` with boolean `recurse_symlinks` argument. The new argument controls whether symlinks are followed when expanding recursive `**` wildcards. The possible argument values correspond as follows:
follow_symlinks recurse_symlinks
=============== ================
False N/A
None False
True True
We therefore drop support for not following symlinks when expanding non-recursive pattern parts; it wasn't requested in the original issue, and it's a feature not found in any shells.
This makes the API a easier to grok by eliminating `None` as an option.
No news blurb as `follow_symlinks` was new in 3.13.
* 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

* Reads zip64 files as produced by the zipfile module
* Include tests (somewhat slow, however, because of the need to create "large" zips)
* About the same amount of strictness reading invalid zip files as zipfile has
* Still works on files with prepended data (like pex)
There are a lot more test cases at https://github.com/thatch/zipimport64/ that give me confidence that this works for real-world files.
Fixes#89739 and #77140.
