Oh, I strongly intend to continue doing this. At times I have maybe
25000+ postfix processes running, spread across a number of systems
running 32bit. On 64bit systems they would gobble up much too much
memory so I would need a lot more boxes.

But if this happens, it is bad coding. Programs do not need to use 64
bit variables just because they are available. They can just as well
keep using as small a variable as they really need.

Another issue is variable packing. The compiler might align small
variables on bigger limits (64 bit?), which would nullify the effort to
conserve memory.
