POV-Ray is developed under Mac OS 9.2.2 so if it would lockup everywhere I
could not develop it, could I?

I saw your bugreport you submitted, and from that I saw that only the render
commands are "slow" for you in a particular slow to render and complex scene
(abyss.pov).  What happens is that it takes until a line has completed to
render until rendering is stopped.  That is why it appears slow for you...

If you really want, you can force the rendering into the background using
this hidden option:

You can control if preemptive threading or cooperative threading is used.
By default cooperative threading will be used.  In order to change this
setting go the the POV-Ray preferences dialog.  Switch to the Editor pane.
Now hold down the "option" key* and switch back to the General pane.  Now
you should see another checkbox:  The checkbox for preemptive threading
which will only take effect after you restart POV-Ray!

While it won't make the rendering faster (unless you have a dual G4), it
will make the whole GUI react immediately as rendering takes place in the
background.  The only catch is that parsing will be a tiny bit slower.

* The "option" key is the one usually marked "alt" on German keyboards, not
sure what it is called on your keyboard...
