Pavel Emelyanov eb43ea2389 restore: Kill CR_STATE_RESTORE_SHARED 
Looks like this separate stage is not needed. The scripts
involved in ns restore are synchronized with existing stages
like this:

criu:                    root task:
ROOT_TASK stage
                         <appear>
"setup-ns" script
PREPARE_NAMESPACES
                         prepare_namespace()
"post-setup-ns" script
FORKING
                         restore_task_mnt_ns()
                         <everything else>

which seems to be OK.

CRIU (Checkpoint and Restore in Userspace)

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.
