The question starts from the fact that in the linux box where killall is 
from psmisc-22.20, if I do (foobar is just a pause() in main)

./foobar &
./hello &
killall foobar

hello is not killed
...
./foobar &
busybox killall foobar

hello is killed

I just wanted to know if it is a "will" or "just happens" in 
find_pid_by_name.
