World files only in tmpfs/shared memory

Enhancement Type

A completely new feature

Describe the enhancement

It would be spectacularly nice if i could store the world folder in RAM so that worldgen doesn't cause as much lag. This feature would obviously require the end user to use backups AND would require that the server restore from backup as a part of startup. Not sure how simple this would be to implement using what you've got, but it would be really nice, as the custom container i build now does this and I'd love to switch to your FAR FAR more mature and organized image here, but don't particularly want to go back to world on disk. :D
