    SubjectRFC [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
