It is very important to keep "Virtual Address Space" and "RAM" out
from each other.
The stacks will use 1.7G of VM-space, but certainly not as much
RAM as most of the stacks are not accessed.
The number you care about is the resident size, the _actual_ amount
of RAM used.
Only on 32bit systems is there any reason to be concerned about
