  Not quite correct.  Any signal will work providing its behaviour is to kill
  the process.  So SIGKILL will always work, and SIGTERM SIGINT SIGQUIT etc
  will work providing that aren't caught or ignored by the process.

If that's true, then the man page is wrong and someone should fix it. I'll
work up a patch if someone can confirm the behavior.
