Kinda hilarious since we've had completely isolated ports for a loooong time. For non-data-intensive tasks, don't underestimate how fast speaking erl_interface over a unix pipe can be. Plus, free isolation, free fault tolerance and free supervision restarting without any networking required.

Here's one of my old examples (no guarantees to its current effectiveness or correctness): https://github.com/mattsta/libgeoip-erlang/blob/master/c_src... — then the whole thing is opened and run from Erlang like https://github.com/mattsta/libgeoip-erlang/blob/70b58ef5ef8a...

It's just cleaner to stay outside direct VM linkage as much as possible.
