The better standard unix tool for examining running processes is 'top',
not 'ps'. By default 'ps' will only show the processes run by the user
himself, not other users nor system processes, and 'ps' will not show
any other info about these processes, while 'top' by default shows all
the top processes running in the system sorted by default by the CPU
time they are taking, which is usually what the user is interested in
(this makes 'top' much more equivalent to the task manager of windows).

  Graphical interfaces usually do not take almost any CPU time at all
if you are not doing anything with them (unless you are using older
versions of MacOS X) so it's usually not necessary or useful to shut
them down for rendering. In order to better establish whether a
graphical interface slows down rendering in any considerable way
(when you are not doing anything but running POV-Ray with it) you
should *test* it, not just assume it.

  Wasn't the image called "First Strike at Pearl Harbour" (unless I have
completely missed a perl joke in that image...)?
  The link http://www.geocities.com/SoHo/Workshop/9193/ doesn't seem
to work...
