killall(1M) System Administration Commands killall(1M)NAME
killall - kill all active processes
SYNOPSIS
/usr/sbin/killall [signal]
DESCRIPTION
killall is used by shutdown(1M) to kill all active processes not directly related to the shutdown procedure.
killall terminates all processes with open files so that the mounted file systems will be unbusied and can be unmounted.
killall sends signal (see kill(1)) to the active processes. If no signal is specified, a default of 15 is used.
The killall command can be run only by the super-user.

killall(8) System Manager's Manual killall(8)NAME
killall - Terminates all processes started by the user, except the calling process
SYNOPSIS
/usr/sbin/killall [- | [-]signal_name | -signal_number]
/usr/sbin/killall -l
FLAGS
The hyphen character (without an argument) sends a SIGTERM signal initially and then sends a SIGKILL signal to all processes that survive
for 30 seconds after receipt of the first signal. This gives processes that catch the SIGTERM signal an opportunity to clean up. A signal
name, optionally preceded by a hyphen, sends the specified signal to processes. The hyphen character (with a signal number argument) sends
the specified signal, either a name, stripped of the SIG prefix (such as KILL), or a number (such as 9). For information about signal
names and numbers, see the signal() system call.
In the System V habitat, the optional signal number does not have to be preceded with a hyphen (-). Lists signal names in numerical order
(as given in the /usr/include/signal.h file), stripped of the common SIG prefix.
DESCRIPTION
This command provides a convenient means of killing all processes created by the shell that you control. When started by the superuser,
the killall command kills all processes that can be terminated, except those processes that started it, the kernel processes, and processes
0 and 1 (init).
Security Configuration
This command is modified in all security configurations of the system.
EXAMPLES
To stop all background processes that have started, enter: killall This sends all background processes signal 9 (the kill signal, also
called SIGKILL). To stop all background processes, giving them a chance to clean up, enter: killall - This sends signal 15 (SIGTERM),
waits 30 seconds, and then sends signal 9 (SIGKILL). To send a specific signal to the background processes, enter: killall -2 This sends
signal 2 (SIGINT) to the background processes. To list the signal names in numerical order, stripped of the SIG prefix, enter: killall -l
This displays a list of signals, which may vary from system to system.

We should put an end to saying "orphan", "kill child", "zombie".

I am having exactly the same problem with https://www.unix.com/programming/129264-application-cleanup-during-linux-shutdown.html but the thread is old and closed. The only difference is that I use sigaction() instead of signal(), which is recommended, as far as I know.
This is my code:
