Nigel said *PER PROCESS* memory. This is limited to an absolute maximum of
4Gb on IA32, because that's the entire address space. (I thought the
division was 3Gb process, 1Gb kernel, though.)
A 64 bit platform (UltraSPARC, Alpha etc.) should support an enormous
amount of memory per process (64 Pb, less kernel requirements?); a 32 bit
one like IA32 is limited to 2-3Gb (2Gb under NT, 3Gb under NT Enterprise
Edition or Linux).
