+Subject: [PATCH] tests/test-captive.sh: Try to make this test more stable on
+ slower machines.
+
+This test relies on sending a signal to nbdkit which causes nbdkit to
+exit before the captive subprocess.  On slow machines (especially
+armv7 and s390x in Fedora Koji) it appears that the captive subprocess
+can still exit before nbdkit receives the signal, resulting in an
+incorrect exit status and test failure.
+
+There's not a lot we can do here except to increase the sleep.
+Alternatives might be to try to inspect the status of the nbdkit
+process to see if it has become a zombie yet, but that would be hard
+to make portable.
+
+Typical failure on armv7:
+
+FAIL: test-captive.sh
