Well, you cannot catch a SIGKILL, but if you want to catch SIGTERM (the
that gets sent by "kill <pid>", here is how to do it:


  [ | sigKillSema |
  sigKillSema := OSProcess accessor forwardSigTerm.
  [sigKillSema wait.
  Transcript show: 'just caught a SIGTERM signal'; cr] repeat]
      fork name: 'SIGTERM watcher process'
