RFC [patch 00/34] PID Virtualization Overview

--
PID Virtualization is based on the concept of a container.
Our ultimate goal is to checkpoint/restart containers.  The
containers should also be useful as a basis for the pid
virtualization required, for instance, by vserver.

The mechanism to start a container 
is to 'echo "container_name" > /proc/container'  which creates a new
container and associates the calling process with it. All subsequently
forked tasks then belong to that container.
There is a separate pid space associated with each container.
Only processes/task belonging to the same container "see" each other.
The exception is an implied default system container that has 
a global view.
The following patches accomplish 3 things:
1) identify the locations at the user/kernel boundary where pids and 
   related ids ( pgrp, sessionids, .. ) need to be (de-)virtualized and
   call appropriate (de-)virtualization functions.
2) provide the virtualization implementation in these functions.
3) implement a container object and a simple /proc interface to create one
4) provide a per container /proc/fs
