funtoo box amd64: BusyBox v1.21.1 (2014-05-09 11:02:02 CEST)
router mips uClibc: BusyBox v1.23.0.git (2014-08-20 11:24:12 CEST)

foobar.c

#include <stdio.h>

int main(int argc,char **argv)
{
     pause();
     return 0;
}

gcc -o foobar foobar.c
ls -s foobar hello

./foobar &
./hello &

busybox ps | grep [f]oobar
19446 root       0:00 ./foobar

busybox ps | grep [h]ello
19447 root       0:00 ./hello

killall foobar
busybox ps | grep [f]oobar
(nothing)

busybox ps | grep [h]ello
19447 root       0:00 ./hello

./foobar &
busybox ps | grep [f]oobar
19474 root       0:00 ./foobar

busybox killall foobar
[5]-  Terminato               ./hello
[6]+  Terminato               ./foobar
(Terminati is killed)

busybox ps | grep [f]oobar
(nothing)

busybox ps | grep [h]ello
(nothing)

The exact sane thing happens on the router.
