However, both sysvinit's and BusyBox's kilall5 make a kill(-1,
SIGSTOP) call before going through the PID list and selectively
sending the requested signal (and I guess Linux does not deliver
SIGSTOP to the process that contains the call, or it would be
pointless), and make a kill(-1, SIGCONT) cal

yes, i had the code in an init once, but i never completed that init.
but dealing with SysV msg queues was not such a big deal from the
code side.
i used it merely as an additional
