of they are zero copy sharing essentially they have both access to same data and this they can screw eachother up. you'd need to design the programs around this... which might aswell make u just use shared memory.

without locking if multiple of these things would read or write to the same place the CPU will not appreciate it... u might read or write partials or garbage etc.?

still a fun little project but i dont see any use case personally. (perhaps the author has a good one, its not impossible)

The author mentioned in a sibling thread that the advantage is that they could be separate executables, which is admittedly a little neat. If processes don't need to share anything then there could be a performance advantage to having them live under the same address space without the overhead of a whole other process.
