For inter-interpreter communication, the worst case scenario is having to rely on a memcpy based message passing system (which would still be faster than multiprocessing's serialisation + IPC overhead)
And memcpy() updates pointer references to dependent objects magically? Surely you meant the memdeepcopy() function that's part of every standard C library!
We already have the tools to do deep copies of object trees [...] "Faster message passing than multiprocessing" sets the baseline pretty low, after all.
What's the goal? 10% faster? Or 10x? copy.deepcopy() uses similar internal mechanisms as pickle... Regards Antoine.
