All you've described is virtual memory.

This works fine if there isn't any sharing of that memory 
with other machines/address spaces.  That is the hard part.
You've also limited your total system data
to the size of your address space, which is 4gb at best.
Any you also must make sure GC doesn't need to
scan over the whole disk-resident world.
