Looking at Terminal.app and it is child processes (login, bash),
when you SIGKILL one of them, for example bash, the child process

SIGKILL the terminal all its child processes are also killed.
Obviously, as SIGKILL is none catchable the SIGKILL is also being
sent by the Kernel to the child processes.
I think the signal is sent to all processes in the same "process
group" - see 'man setpgid'
