On the self-hosted KVM runner Docker is on PATH but the daemon socket is unreachable (firewalled/dropped). subprocess.run(["docker", "info"]) with no timeout hangs indefinitely on a dropped connection, stalling the coverage job for hours — one hang per @skip_unless_docker()-decorated class, ~8 per integration suite run. Add timeout=5 with a TimeoutExpired → False fallback so the check resolves quickly to "unreachable" rather than blocking.
