Mmm, ok; I didn't read it that way.

If you've a per-process 4 GiB limit and a system with more that 4 GiB
memory, then the swapper would only kick in if the system itself was
needing swap. In which case it doesn't matter whether you're running
32-bit PAE or true 64-bit. The per-process limit simply prevents the
application growing beyond that fixed limit.
