One thing I was able to do a few years ago was pull data from badly corrupt media. Linux would panic on read (and sometimes on mount), same for FreeBSD and NetBSD.
So I decided to try Rump on NetBSD think "what the heck". I read up on it, loaded it, crash. But the system stayed active so I tried again and again, after multiple tries I was able to get 90% of the file. Saved me from trying to re-create the doc.
It is not a container or a jail but something unique, you can use it to develop/test things that would crash a system.
