Its not a new technique - if you allocate memory "handlers" rather than
addresses and ask the OS/Memorymanager to lock a handler in memory
(and give you an address) then the OS/MM is able to move around unlocked
memory blocks, even on/off disk, at whim.
Win16 memory allocation looked like this, and I'm sure it was lifted
from something even older.
Its not actually a bad idea in a single-process standalone application.
It certainly beats using a VM in this instance.
Anyway, back to the network topics.
