tests/test_xdist_handling.py fails with PyTest 8.0.2 and Python 3.12 in Debian CI environment: tries stat on /tmp/systemd-private-xxx #110
Description
A bizarre error, which you may have some insight into. I obtain the same error if I use 1.2.0 or the current HEAD (commit a568bb1):

The tests are called as python3.12 -m pytest tests perf_tests in a directory only containing copies of perf_tests and tests.
If you have any idea what might be causing this, I'd be very grateful! It doesn't seem to make any sense that something should be looking in this systemd-private directory.
