  Perhaps, but it would be a good idea to send a SIGINT to povray instead
of SIGKILL (I think that's the default?), ie. "kill -s INT".
  Povray caches SIGINT and saves the currently calculated image (which may
be in a buffer) before terminating.
  (Well, actually I don't know if it also caches other signals...)
