+Subject: Terminate individual tests after half an hour
+
+While using the Automake parallel test harness, if a test hangs for
+long enough for an external watchdog to kill the entire build process
+(as happens in Debian sbuild after 150 minutes with no activity on
+stdout/stderr), the logs will not be shown. If we make an individual
+test time out sooner, logs are more likely to be shown.
