Use `ma_used` instead of `ma_keys->dk_nentries` for modification check
so that we only check if the dictionary is modified, not if new keys are
added to a different dictionary that shared the same keys object.

gh-67022: Document bytes/str inconsistency in email.header.decode_header() and suggest email.headerregistry.HeaderRegistry as a sane alternative (GH-92900)
* gh-67022: Document bytes/str inconsistency in email.header.decode_header()
This function's possible return types have been surprising and error-prone
for the entirety of its Python 3.x history. It can return either:
1. `typing.List[typing.Tuple[bytes, typing.Optional[str]]]` of length >1
2. or `typing.List[typing.Tuple[str, None]]`, of length exactly 1
This means that any user of this function must be prepared to accept either
`bytes` or `str` for the first member of the 2-tuples it returns, which is a
very surprising behavior in Python 3.x, particularly given that the second
member of the tuple is supposed to represent the charset/encoding of the
first member.
This patch documents the behavior of this function, and adds test cases
to demonstrate it.
As discussed in bpo-22833, this cannot be changed in a backwards-compatible
way, and some users of this function depend precisely on the existing
behavior.
Add warnings about obsolescence of 'email.header.decode_header' and 'email.header.make_header' functions.
Recommend use of `email.headerregistry.HeaderRegistry` instead, as suggested
in https://github.com/python/cpython/pull/92900#discussion_r1112472177

gh-132969: Fix error/hang when shutdown(wait=False) and task exited abnormally (GH-133222)
When shutdown is called with wait=False, the executor thread keeps running
even after the ProcessPoolExecutor's state is reset. The executor then tries
to replenish the worker processes pool resulting in an error and a potential hang
when it comes across a worker that has died. Fixed the issue by having
_adjust_process_count() return without doing anything if the ProcessPoolExecutor's
state has been reset.
Added unit tests to validate two scenarios:
max_workers < num_tasks (exception)
max_workers > num_tasks (exception + hang)

* gh-91048: Reorder result tuple of parse_code_object (GH-134898)
Reorder result tuple of parse_code_object
The standard followed by APIs like pstat.Stats is to take a file, line,
function triplet. The parse_code_object function (and callers exposing
this in Python like RemoteUnwinder.get_stack_trace) return function,
file, line triplets which requires the caller to reorder these when
using it in classes like pstat.Stats.
