This is really big (if it works!)—a big limitation for the use of R in simulation up to this point has been memory bloat. I’ve had to turn off parallel processing/reduce the number of workers many times in my {targets} workflows due to OOM errors. Hopefully this will solve that problem

mori is a new R package for sharing R objects across processes via OS-level shared memory. Parallel workers get zero-copy, lazy ALTREP access to the same physical pages — share once, read anywhere.
