One can run multiple processes on multi-cored CPUs.
Shared memory isn't necessarily all that great a model,
but is difficult to avoid with threads.
Separate processes with explicit message-passing
can be a lot easier to wrap one's brain around.
The lack of a common address space makes it
hard for them to tromp on each others data.
