I'm not a linux thread expert, but from what I know Linux doesn't know lightweight threads as other systems do. Instead it uses processes for that. But these processes aren't "top level" processes that show up in top/ps. Instead, they're grouped hierarchically (AFAIK). Otherwise you would be able to kill single user threads with their own process id, or kill the main process and let the spawned threads continue. That would be totally crazy. In my configuration, Tomcat doesn't shut down correctly if I call bin/shutdown.sh, so I have to kill the process manually. I don't know why. This might be the reason why stockii has 3 Tomcat processes running.
