That's of no use without a dynamic allocator, I think. Or else it is a 
vague description of a dynamic allocator.

I'm approaching the problem from another perspective: trying to 
implement a dynamic allocator on top of a fixed size memory pool, first. 
Once we have that, we may start to think about dynamically adding or 
removing underlying segments.
