gh-119592: Fix ProcessPoolExecutor stranding submitted work when a max_tasks_per_child worker exits
Worker replacement went through the executor object: the manager thread
read executor attributes that shutdown(wait=False) clears concurrently,
and could not replace workers at all once the executor was garbage
collected. A worker exiting at its max_tasks_per_child limit in those
states left the remaining submitted work permanently unexecuted and hung
interpreter exit; the racing case could crash the manager thread.
Replace workers from the executor manager thread using its own state
plus configuration read through the live executor weakref, which
shutdown() never clears:
- After shutdown(wait=False) with the executor still referenced, a
replacement is spawned and the remaining work is executed as
documented.
- Once the executor has been garbage collected (gh-152967), or a
replacement worker cannot be started and no workers remain, the
remaining futures now fail with BrokenProcessPool instead of never
resolving.
- A new _force_shutting_down flag stops both spawn paths from starting
workers that would escape terminate_workers()/kill_workers().

[3.15] gh-143990: Preserve the size when creating a Font from a named font (GH-153267) (GH-153323)
tkinter.font.Font now copies the options of a named font (via "font
configure") instead of the options resolved by "font actual", which
would resolve a size specified in pixels (a negative size) to points.
A font description is still resolved, as it cannot be parsed otherwise.
Font.copy(), which has always been equivalent to constructing a Font
from the original font, is updated to match and now preserves the size
too.

corrupting a response that ends with a literal (such as a mailbox name
returned by LIST): its empty trailer was mistaken for the blank and the

The blank is now skipped only inside an unclosed parenthesis. After a
literal that ends the response it instead arrives before the next
response and is skipped there.

gh-153056: Fix a data race compiling the string.Template pattern in free-threading builds (GH-153057)
* gh-153056: Fix a data race compiling the string.Template pattern in free-threading builds
Template compiles its substitution pattern lazily and caches it on the class. On the free-threaded build two concurrent first uses could race: a thread that observed the pattern another thread had just compiled would try to recompile it, and re.compile() rejects flags on an already-compiled pattern, raising a spurious ValueError. Return the already-compiled pattern instead.
As a side effect, a subclass that supplies an already-compiled pattern now works too; previously it raised the same ValueError at class definition.
* Trim test comments and NEWS wording
* Document that the pattern attribute accepts a string or a compiled regex
* Comment the three states of pattern and note the documented-behavior fix in NEWS

[3.15] gh-152682: Fix NULL dereference on OOM in `symtable_visit_type_param_bound_or_default` (GH-152684) (#152695)
In `symtable_visit_type_param_bound_or_default()`, when a reserved name
(e.g. `__classdict__`) is used as a type parameter, `PyUnicode_FromFormat()`
is called to build the SyntaxError message. If the allocation fails and
returns NULL, the subsequent `PyErr_SetObject()` and `Py_DECREF()` calls
would dereference NULL, causing a segfault.
Fix by returning 0 immediately when `PyUnicode_FromFormat()` returns NULL.
This propagates the MemoryError set by `PyUnicode_FromFormat()`.

[3.15] gh-40038: Quote imaplib command arguments when necessary (GH-152703) (GH-153066)
Argument quoting was inadvertently disabled when imaplib was ported to
Python 3 (bpo-1210 commented out the ``_checkquote()`` call, bpo-9638
then removed it), so since Python 3.0 commands failed for arguments
containing protocol-sensitive characters, such as a space in a mailbox
name.
Quoting is restored and reimplemented per the RFC 3501 grammar, so that
arguments that need quoting are escaped and quoted, while flags, sequence
sets and list wildcards are left intact.
For backward compatibility, an argument already enclosed in double quotes
is left unchanged, so code that quotes arguments itself keeps working.

The hang this test guards against (interpreter exit after

comment claiming ProcessPoolExecutor often hangs with wait=False.

gh-115634: Fix ProcessPoolExecutor deadlock with max_tasks_per_child (GH-140900)
The idle worker semaphore counts task completions, not idle workers, so
it can hold a stale token released by a worker that later exited upon
reaching its max_tasks_per_child limit. The worker replacement path
consumed such tokens and skipped spawning a replacement, deadlocking
the remaining queued tasks once no workers were left.
Replace dead workers based on len(self._processes) without consulting
the semaphore. The submit() path is unchanged, preserving on-demand
spawning and idle worker reuse.

idlelib submodules as top-level modules, such as "import help".
