But if you are sending a SIGKILL signal I think the only way is by  
using the killall5 program.  It isn't included in busybox, but  
essentially it does:

i=0
while [ 0$i -lt 40000 ]; do
	echo killing group $i;
	[ $i -eq $$ ] || kill -$i
	i=$(( $i + 1 ));
done

So it kills all the process groups except the current one.
