+Subject: [PATCH] tests: fix job control triggering test termination
+
+This avoids the test harness being terminated like:
+  make[1]: *** [Makefile:24419: check-recursive] Hangup
+  make[3]: *** [Makefile:24668: check-TESTS] Hangup
+  make: *** [Makefile:24922: check] Hangup
+  make[2]: *** [Makefile:24920: check-am] Hangup
+  make[4]: *** [Makefile:24685: tests/misc/usage_vs_refs.log] Error 129
+  ...
+
+This happened sometimes when the tests were being run non interactively.
+For example when run like:
+
+  setsid make TESTS="tests/timeout/timeout.sh \
+   tests/tail/overlay-headers.sh" SUBDIRS=. -j2 check
+
+Note the race window can be made bigger by adding a sleep
+after tail is stopped in overlay-headers.sh
+
+The race can trigger the kernel to induce its job control
+mechanism to prevent stuck processes.
+I.e. where it sends SIGHUP + SIGCONT to a process group
+when it determines that group may become orphaned,
+and there are stopped processes in that group.
+
+* tests/tail/overlay-headers.sh: Use setsid(1) to keep the stopped
+tail process in a separate process group, thus avoiding any kernel
+job control protection mechanism.
+* tests/timeout/timeout.sh: Use setsid(1) to avoid the kernel
+checking the main process group when sleep(1) is reparented.
+Fixes https://bugs.gnu.org/80477
