* Implement _collections.OrderedDict
Extracted from #6799: native OrderedDict as a dict subclass,
iterator mutation tracking, and mapping-view set operations.
* Add OrderedDict, warnings source lines, and socket sendmsg
Implement _collections.OrderedDict as a dict subclass with a
linked list of insertion-order nodes.
Pack struct F/D as native float/double complex pairs, and report
unexpected __replace__ field names as a list repr.
Register encodings.latin_1 at startup. Reject NUL in input()
prompts. Copy non-exact type dicts in mapping order.
Fetch warning source lines through _bless_my_loader and unicode
splitlines. Keep the last warnings.filters list after deletion.
Snapshot sendmsg sequences before converting buffers, parse
ancillary ints with __index__, and dispatch AF_CAN by protocol.
Store sys.trace and sys.profile on each ThreadSlot so
_settraceallthreads/_setprofileallthreads are visible to
sys.gettrace/getprofile on other threads.
Use <frozen importlib._bootstrap> as frozen importlib
co_filename. Keep HEAPTYPE socket objects GC-tracked.

* Load marshal via readinto and dump sets in dumps order
marshal.load fills a scratch buffer with readinto on a
contiguous writable memoryview, and rejects a returned length
other than the requested size.
set and frozenset dumps write elements in sorted(v,
key=marshal.dumps) order.

* Add classmethod_descriptor and ABC IS_ABSTRACT flags
Give METH_CLASS methods a distinct classmethod_descriptor type.
Store Py_TPFLAGS_IS_ABSTRACT from __abstractmethods__ and look
up that attribute only in the type's own dict.
Expose defaultdict.default_factory as a member descriptor.
Inherit bool's unused number slots from int. Mark set and
frozenset __contains__ as METH_COEXIST.
Parse classmethod, staticmethod, object.__new__, and heap type
text signatures. Register interactive source in linecache.

* address review: odict reuse, descr call, new wrapper
Reuse odict node slots and walk the live list in next_after.
Require both | operands to be dicts. Drop the odict iterator
on GC clear. Bind classmethod descriptors through descr_get
and update IS_ABSTRACT under the type lock. Give odict keys
and items sq_contains. Walk tp_new_wrapper past new_wrapper
so HEAPTYPE socket subclasses can call socket.__new__.
Split FreeBSD Bluetooth protocol constants from Linux values.

* Disallow instantiation of sys.getwindowsversion type
Add slot_new to PyWindowsVersion that raises TypeError,
matching sys.flags behavior.
* Remove incorrect WSAHOS errno constant
WSAHOS was hardcoded as an alias for WSAHOST_NOT_FOUND, but
CPython guards it with #ifdef WSAHOS which doesn't exist in
modern Windows SDK headers.
* Fix mmap resize to raise OSError instead of SystemError
* Fix CreateProcess with empty environment on Windows
Empty env dict produced a single null terminator, but
CreateProcessW requires a double null for a valid empty
environment block.
* Revert mmap resize error to SystemError and fix errno.rs formatting
mmap resize raises SystemError (not OSError) when mremap is unavailable,
matching CPython behavior. test_mmap catches SystemError to skip unsupported
resize operations.
* Fix named mmap resize to raise OSError and unmark test_sleep expectedFailure
Named mmap resize on Windows should raise OSError (not SystemError).
Remove expectedFailure mark from TimeEINTRTest.test_sleep as it now passes.
* Use expectedFailureIf for TimeEINTRTest.test_sleep on Linux
test_sleep passes on macOS but fails on Linux due to timing.

test_sleep now passes on all platforms.

* rewrite finalize_modules with phased algorithm
Replace the absence of module finalization during interpreter shutdown
with a 5-phase algorithm matching pylifecycle.c finalize_modules():
1. Set special sys attributes to None, restore stdio
2. Set all sys.modules values to None, collect module dicts
3. Clear sys.modules dict
4. Clear module dicts in reverse import order (2-pass _PyModule_ClearDict)
5. Clear sys and builtins dicts last
This ensures __del__ methods are called during shutdown and modules are
cleaned up in reverse import order without hardcoded module names.
* dealloc the rigth way
* fix finalize_modules: only clear __main__ dict, mark daemon thread tests as expected failure
Without GC, clearing all module dicts during finalization causes __del__
handlers to fail (globals are None). Restrict Phase 4 to only clear
__main__ dict — other modules' globals stay intact for their __del__
handlers.
Mark test_daemon_threads_shutdown_{stdout,stderr}_deadlock as expected
failures — without GC+GIL, finalize_modules clears __main__ globals
while daemon threads are still running.
