os.execvp on windows doesn't wait for the executed program to finish and doesn't report it's exit code

Bug report

os.execvp on windows doesn't wait for the executed program to finish and doesn't report it's exit code. Code:

import os
import sys

if len(sys.argv) > 1 and sys.argv[1] == "my_argument":
    sys.stderr.write("my_argument detected. Exiting with code 1.\n")
    sys.exit(1)
else:
    sys.stderr.write("no argument detected. Calling os.execvp\n")
    os.execvp(sys.executable, [sys.executable] + sys.argv + ["my_argument"])

bat file:

@echo off
python exec.py
if %errorlevel% NEQ 0 (
    echo The script gave exit code %errorlevel%
) else (
    echo Error: The script exited with exit code 0
)

Output from command prompt:

C:\pythonizer\play>exec.bat
no argument detected. Calling os.execvp
Error: The script exited with exit code 0

C:\pythonizer\play>my_argument detected. Exiting with code 1.

Note the command prompt prompted me for a new command before the exec'd process wrote out it's message.

Your environment

• CPython versions tested on: 3.10.6
• Operating system and architecture: Windows 10

Inizia riproducendo il comportamento di Windows 10 con lo script Python e il file batch forniti, quindi traccia il punto di ingresso os.execvp e la relativa implementazione Windows. Il lavoro è completato quando il programma eseguito termina prima che il file batch prosegua e il suo codice di uscita diverso da zero viene segnalato al chiamante.
