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

Comece reproduzindo o comportamento do Windows 10 com o script Python e o arquivo batch fornecidos e, em seguida, rastreie o ponto de entrada os.execvp e sua implementação para Windows. Considera-se concluído quando o programa executado termina antes de o arquivo batch continuar e seu código de saída diferente de zero é relatado ao chamador.
