What inter processor synchronization issues are there? Could you take
this a step further and use processes on different machines for each
processor? (There are many shared memory implementations to choose
from.) I have ignorantly implemented an SH2 emulator, but have zero
understanding of an SMP system. Are there so many resources shared
between the CPUs to make this a ridiculous proposition?
It could make for a interesting distributed single image system.
