A user space program can checkpoint itself. Many do. This project is about checkpointing an application that wasn't designed for checkpointing, which I suppose saves the enormous engineering effort of building application-specific checkpointing into all the applications.

CyroPID is a user-space application that can checkpoint other processes without any special support. It doesn't work for all cases, although it's good enough for the "D'oh! I forgot to start this application inside screen(1)" use-case.
