[Cialug] "stuck" process

[Bryan Baker]

Yup, -9 == KILL

      Some of the more commonly used signals:
      1       HUP (hang up)
      2       INT (interrupt)
      3       QUIT (quit)
      6       ABRT (abort)
      9       KILL (non-catchable, non-ignorable kill)
      14      ALRM (alarm clock)
      15      TERM (software termination signal)
