Did you even read the whole thing? Because you should... the first four
lines don't tell all there is to know about it. Read further and be
educated: "The 32-bit size of the virtual address is not changed, so
regular application software continues to use instructions with 32-bit
addresses and (in a flat memory model) is limited to 4 gigabytes of
virtual address space."
Just as Brett said: "You are still limited to a 32bit address space in
the process so you still can't go over the 4Gb memory limit"
