[issue39327] shutil.rmtree using vagrant synched folder fails

Peter Liedholm  added the comment:

Problem is also reported in virtualbox
https://www.virtualbox.org/ticket/19004

>From that ticket some more analysis is done;
strace reveals that Python has kept an open fd for the directory being removed.

[issue39340] shutil.rmtree and write protected files

[Peter Liedholm]

New submission from Peter Liedholm :

Ubuntu 18.4 and Windows 7 has different behaviour when deleting write protected 
files with rmtree.

Ubuntu silently deletes them (unexpected?)
Windows moans about access denied (expected?)

Reproduction method linux
mkdir test; touch test/file.txt; chmod -w test/file.txt

Reproduction method windows
mkdir test && type nul > test\file.txt && attrib +R test\file.txt

Reproduction method cont.
python3 -c "import shutil; shutil.rmtree('test')"

Peter Liedholm  added the comment:

What I would expect is a consistent behaviour and as a user I am not interested 
in inner guts of differences between filesystems.
