New submission from Toshihiro Kamiya <kam...@mbj.nifty.com>:
When I was writing unit tests, I noticed that os.chdir in the unittest test
case failed with RecursionError.
It seems to work fine on Ubuntu 20.04, but fails on Windows 10 (might fail on
macOS).
The attached file is a minimal code to reproduce this.
When I run it, I got an error message as follows
```
PS C:\Users\toshihiro\tmp> python .\test_chdir_fails.py
Traceback (most recent call last):
File "C:\Users\toshihiro\tmp\test_chdir_fails.py", line 11, in <module>

The version of python was:
Python 3.9.5 (tags/v3.9.5:0a7dcbd, May 3 2021, 17:27:52) [MSC v.1928 64 bit
