Indeed, on i386 the virtual address space is 4GB, but it gets fragmented by various security techniques like W^X (..NX bit simulation) which had to be implemented using segmentation tricks.

This change at least allows a process to use a little more memory, although login.conf still need to be tweaked for that.
