Ah, so this means all subprocesses completed, allowing the wait to exit. The disowned process then had nothing to kill because the script had already finished.
You can just add a
sleep 2
to the end so you don't get this message. Or, you can redirect the kill's stderr to /dev/null.

mysql_waitpid
MYSQL_WAITPID(1) MySQL Database System MYSQL_WAITPID(1)
NAME
mysql_waitpid - kill process and wait for its termination
SYNOPSIS
mysql_waitpid [options] pid wait_time
DESCRIPTION
mysql_waitpid signals a process to terminate and waits for the process to exit. It uses the kill() system call and Unix signals, so it runs
on Unix and Unix-like systems.
Invoke mysql_waitpid like this:
shell> mysql_waitpid [options] pid wait_time
mysql_waitpid sends signal 0 to the process identified by pid and waits up to wait_time seconds for the process to terminate. pid and
wait_time must be positive integers.
If process termination occurs within the wait time or the process does not exist, mysql_waitpid returns 0. Otherwise, it returns 1.
If the kill() system call cannot handle signal 0, mysql_waitpid() uses signal 1 instead.
mysql_waitpid supports the following options:
o --help, -?, -I
Display a help message and exit.
o --verbose, -v
Verbose mode. Display a warning if signal 0 could not be used and signal 1 is used instead.
o --version, -V
Display version information and exit.
