partd/tests/test_zmq.py . !! Copr timeout => sending INT
Copr build error: Build failed]: [It shows the progress of tests run.]

Issue: There seems to be a problem causing the tests to get stuck, and then the build reached the limit of 5 hours and got killed by COPR.
Resolution: Find the test that hangs and figure out what is wrong with it, or skip it.
