That's very interesting. Userfaultfd opened a lot of features in Linux.
When I saw 'unfork' I thought 'someone found out how to replace the current process with a child process that was a older snapshot'. Any idea on how to do this? Like 'OK I did something wrong, let me back up a bit, kill me, replace me with my child x and refather every other one of my children processes to child x and gooo'.
