Description
Running the Django test suite against the Python 3.11 pre-releases, we have hit
a potential regression.
Steps to reproduce
git clone https://github.com/django/django.git
python3.11 -m venv env
.\env\Scripts\Activate.ps1
python -m pip install -e django
cd django\tests
python runtests.py --parallel
Bug report
On Python 3.8, 3.9, and 3.10 this runs without problem.
On Python 3.11 the following error in seen after the test suite completes,
during shutdown:
Traceback (most recent call last):

os.remove(test_database_name)
PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'other_1.sqlite3'
This looked similar to us to open issue #95027 but we were asked to report it
separately.
I've tested all the way back to a1 where (along with other issues now resolved)
this error still occurs:
(django-py311) PS C:\Users\carlt\src\django\tests> python --version
Python 3.11.0rc2
...
(django-py311) PS C:\Users\carlt\src\django\tests> python --version
Python 3.11.0a1
This is somewhat frustrating as we've tried to test on all platforms since the
first releases.
Our test suite would only run on Windows with Python 3.11 very recently as
there was a third-party dependency that was not compatible with Windows. We
will try to adjust to test without dependencies as well on Windows for future
versions. (Sorry about that.)
Please do let us know if we can provide further info. I imagine though the
easiest thing is for you to run this yourself.
Thanks.
