  If I'm not completely mistaken, you can have up to 16 or 64 gigabytes
(I don't remember which) of physical RAM in a pentium or newer processor.
Of course one process can address only 4 gigabytes at a time. (To be able
to use all the memory the processor provides a memory paging system.)

  So indeed, you could even have more than 4 gigabytes of physical RAM,
yet a 32-bit POV-Ray binary could only allocate 4 gigabytes of it at most
(if the OS allows it).
