…the bytecode (python#136525) Previously, we assumed that instrumentation would happen for all copies of the bytecode if the instrumentation version on the code object didn't match the per-interpreter instrumentation version. That assumption was incorrect: instrumentation will exit early if there are no new "events," even if there is an instrumentation version mismatch. To fix this, include the instrumented opcodes when creating new copies of the bytecode, rather than replacing them with their uninstrumented variants. I don't think we have to worry about races between instrumentation and creating new copies of the bytecode: instrumentation and new bytecode creation cannot happen concurrently. Instrumentation requires that either the world is stopped or the code object's per-object lock is held and new bytecode creation requires holding the code object's per-object lock.
Make grp module methods getgrgid() and getgrnam() thread-safe when the GIL is disabled and getgrgid_r()/getgrnam_r() C APIs are not available. --------- Co-authored-by: Kumar Aditya <kumaraditya@python.org>

…is not available. (pythonGH-131201) Fix "msvcrt" import warning on Linux when "_ctypes" is not available. On Linux, compiling without "libffi" causes a "No module named 'msvcrt'" warning when launching PyREPL.

…GC (pythonGH-136009) This helps catch double deallocation bugs and is similar to the assertion in the GIL-enabled build. The call to `validate_refcounts` is moved up to start of the GC because `queue_untracked_obj_decref()` creates it own zero reference count garbage.
It was "doctest.module attribute". Now it is "module attribute".
__test__ = None is not supported since Python 2.4.

…6706) Provide a stub implementation of umask that is enough to get some tests passing. More work is needed upstream in Emscripten to make all umask tests to pass.
…n#136708) Makes the Emscripten stack overflow skip message consistent with WASI, and replaces some ad-hoc skips.
…nymore (python#136707) This might have been fixed by pythongh-136624, or by some Emscripten change. In any case, it no longer seems to be needed.
`_asyncio` is now built as a static module so that thread states can be accessed directly via registers and avoids the overhead of function call.
