[issue44013] tempfile.TemporaryFile: name of file descriptor cannot be reused in consecutive initialization

[Xiang Zhong]

New submission from Xiang Zhong <zhongxiang117 at gmail.com>:

The variable of instance cannot be reused in two consecutive codes chunk combinations. Please check the difference in attached file, xtempfile.py, function: test_3 & test_4.

However, surprisingly, the problem can be fixed in test_5 and test_6.

Which may be helpful for debug: why does the value of "id(fd.name)" keep constant all the time inside those combinations?
