Tikhomirov Pavel e01dc7faa6 v2 mem: if no parent image persists, can't rely on it 
here was bug cause if e.g.: iterative snapshots are made and
between two of them new process in process tree was created,
it can have pages which are non dirty, and won't save them
into image. but there is no parent image for it.

pages which are non soft-dirty appear if process with some pages
in non dirty state forks, child will inherit those pte's
and if child don't write to those pages, they will be still in non
soft-dirty state when next dump comes.

also this bug was not catched because of error in zdtm, look 3/3

v2: simplify, add more justification in commit message.

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
