perl-Redis-1.991-10.fc31 fails to build in F31:

Result: PASS
RPM build errors:
BUILDSTDERR: error: Bad exit status from /var/tmp/rpm-tmp.tdIwBR (%check)

It seems rpm-build appends some script after a %check section that tries to
clean up running processes and there is a race between gathering PIDs and
killing them.

This seems to be triggered up upgrading rpm-build from 4.14.2.1-10.fc31 to
4.14.90-0.git14653.13...

Maybe he %check script should wait() on the daemon PID after killing it.

--- Comment #1 from Panu Matilainen <pmatilai(a)redhat.com&gt; ---
This is an rpm bug, it shouldn't error out because a process we were about to
kill died on its own.

If you want to wait on the pid, you're of course free to do so anyway.
