New submission from R0b0t1 <s...@aeam.us>:
Using `os.walk` to traverse a filesystem on Windows does not terminate in the
case of a recursive mountpoint existing somewhere in the path.
In my case C:\circlemount is linked to C:\, producing paths such as
C:\circlemount\circlemount\circlemount\circlemount\...
A drive mount point may be set up as follows:
```diskpart (enters shell)
list volume`
select volume ${#}`
assign mount=${path}
```
Notably this only happens for Win32 python. Cygwin and MSYS2 pythons as well as
the pythons distributed with some packages like Inkscape behave properly.
