This would be like running Elisp in a separate process, except that it's not a separate process, so communication between two containers can be very efficient (e.g. you can send a buffer from one container to the other as efficiently as you can send an integer). Potential applications: - true concurrency - safely running arbitrary Elisp code (e.g. bug#32495) - discover what a package defines without actually defining those things (i.e. load the package into a container, then look at what got defined and throw away the container).
