Delegating memory operations to lower layers in the hierarchy is one of=20

You typically start with shared atomic operations and very simple=20
computation, like a LOCK XADD, then once you are on this slippery slope=20
you quickly decide to add more advanced capabilities, quickly ending up=20
with something like Bunny Chang's distributed virtual machine which can=20
securely distribute its code anywhere in the cluster.

Taken to its extreme, any cloud datacenter works this way, but at a far=20
higher granularity.
