It is not that useful to have that large amounts of swap as long as
processes are limited to 32-bit addressing space. It could be very
useful on 64-bit ports -- do those ports have the same limit?

However, I think it is reasonable to support >128M swap in one area.
I usually configure our servers with 250MB of swap space, and those
servers are by no means high-end.
