-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
