NOTE: I think you have to run this as an admin b/c ServiceHandle seems to
      be null when not elevated. Also, this can't be used to get the SACL
      (ServiceHandle probably isn't opened with that access requested, and
      this code doesn't do privilege modifications). If you really want to
      get around these problems, you can probably use reflection to get at
      the GetServiceHandle() private method on the ServiceController 
      instance. That might work as a non-elevated user...
