Pavel Emelyanov bda033e1e9 criu: Version 1.4 
So, according to the recently accepted plan we have 1.4.

Biggest achievement here is that we've finally started with
user namespaces, fixed CRIU to work smoothly with the p.haul
project and optimized images and /proc files IO.

And a bunch of bugs, of course.

README 

criu
====

An utility to checkpoint/restore tasks. Using this tool, you can
freeze a running application (or part of it) and checkpoint it to
a hard drive as a collection of files. You can then use the files
to restore and run the application from the point it was frozen
at. The distinctive feature of the CRIU project is that it is
mainly implemented in user space.

The project home is at http://criu.org

Pages worth starting with are
* Kernel configuration, compilation, etc: http://criu.org/Installation
* A simple example of usage: http://criu.org/Simple_loop
* More sophisticated example with graphical app: http://criu.org/VNC
