all of the difficulties I foresee have to do with multiprocessing/sharing/context switching... I'd like to be able to park a high performance actor on a particular CPU, and have it consuming its "inbox" queue, no context switches necessary. my guess is that only one logical program can use the scratchpad at a time? How about registers or a scratchpad which has async pub/sub semantics? One CPU can write, and the rest can read? A mechanism like that would use the same hardware which already supports cache coherency, but would let programmers forget about a lot of potential headaches.
