500ms fork of a running VM with full memory state is the kind of thing I'd assume wasn't possible until I saw it work. What does failure look like — does the fork just not happen, or can you get partial state?
There is no partial state really possible. We can run out of space on a Node and just say no. But the nature of memory forking is if you don't literally do it 100% right it crashes immediately (I know cuz it took me a while too get it right).
