New submission from STINNER Victor: subprocess.Popen has a race condition on Windows with file descriptors: if two threads spawn subprocesses at the same time, unwanted file descriptors may be inherited, which lead to annoying issues like "cannot delete a file because it is open by another process". For the issue #19575 for an example of such bug.
Since Windows Vista, a list of handle which should be inherited can be specified in CreateProcess() using PROC_THREAD_ATTRIBUTE_HANDLE_LIST with STARTUPINFOEX. It avoids the need to mark the handle temporarly inheritable.
