tests fail on resource.setrlimit

When running the test suite for 3.1.0 (with Python 3.8 on openSUSE/Factory) I get:

I run the build in the limited chroot (prescribed for building openSUSE packages), so it is possible that some resources is not available.

Any ideas, what to do (aside from attaching @unittest.skip to all those tests)?

This doesn't seem to be a problem any more.
