The purpose of this issue is to avoiding having to call CreateProcess() with bInheritHandles parameter set to TRUE on Windows, and avoid calls to self._make_inheritable() in subprocess.Popen._get_handles(). Currently, bInheritHandles is set to TRUE if stdin, stdout and/or stderr parameter of Popen constructor is set (to something else than None). Using PROC_THREAD_ATTRIBUTE_HANDLE_LIST, handles don't need to be marked as inheritable in the parent process, and CreateProcess() can be called with bInheritHandles parameter set to FALSE.
