Checkpoint/restart in the userspace

Abstract

Checkpoint/restart is the ability to save tasks state in some plate to later restore one. There have been several attempts of having this functionality in kernel but none of them succeeded so far. Recently OpenVZ engineers has proposed the mostly-in-the-userspace approach to the problem which looks promising

The aim of the discussion is to find out ways for further c/r implementation.
