Why should we support nodes with no memory? If a node has no memory then
its processors and other resources need to be attached to the nearest node
with memory.
AFAICT The primary role of a node is to manage memory.
A node is an arbitrary container object containing one or more of:
CPUs
Memory
IO bus
It does not have to contain memory.
