I don't know about Java (there might be components of the Java system 
wrongly running with increased priority) but apart from that this would 
be extremely unusual.  Unless you are running out of memory of course - 
since there is nothing like priority for swapping exceeding available 
memory will always slow down the whole system.  Also note Gimp uses its 
own 'virtual memory' system so you should make sure its settings are 
appropriate.

You can easily test if a slowdown you experience during a POV-Ray render 
is due to POV-Ray 'eating up' CPU time - run it with lowest priority 
('nice -19 povray' instead of 'povray') and see if this changes 
anything.  If not a hypothetical pause function in POV-Ray would not 
help either.
