What if you have more than 3Gb of RAM to play with... would you have to use
amd64 then?
You could use PAE (Physical Address Extensions) on i386. That gives the CPU
access to 64 GB. But that does not mean all that address space is
available for programs.
It does not influence the standard limits on process sizes though. See
/sys/<arch>/include/vmparam.h and /sys/conf/NOTES.
