The idea is to put the different memory areas (tempOb, data stack, return stack, temporary variables) at distant locations from each other in the address space. When one area needs to grow we'll tell the MMU to map a page to it. This will be much faster than the traditional RPL method of packing memory areas next to each other and possibly moving them when one area needs to grow.

Memory management is isolated in the code so I suspect we could do it in a system without an MMU also.
