test_events_watched_outside_test_are_ignored fails with PermissionError

I am currently trying to package asynctest-0.12.2 for Gentoo Linux and I am running into a test error:

======================================================================
ERROR: test_events_watched_outside_test_are_ignored (test.test_selector.Test_fail_on_active_selector_callbacks)

During handling of the above exception, another exception occurred:

I acquired the source tarball from PyPI and executed the test with the command PYTHONPATH=. python3.6 -m unittest --verbose test. All other tests run successfully.

Am I doing something wrong or can you reproduce the issue, too?

Hey! Hehe, I am trying to pack this python package into Gentoo too! 😃 My gentoo bug is https://bugs.gentoo.org/669272 What is your gentoo bug or pull request? So we do not do the same job twice.

I am also having the same issue. If I discover anything worthwhile I’ll post here.

Interestingly enough, if I enter the build container using mock -r fedora-rawhide-x86_64 shell and run the testsuite manually (PYTHONPATH=$(pwd) python3 -m unittest test) it doesn’t fail.
