Greg ...

In our pid virtualization patches we removed the object automatically.
I presume that Kirill does the same .... although the code for that is not released.

I am working on converting our pid stuff so to follow the recommendation of Linux/Alan
to just do <container,pid> isolation through pidspaces.

I could release an allocation/ before hand. Based on Kirill's 1/5 patch adoption
(which took Linus's & Dave's naming comments into account)

How do we want to create the container?
In our patch we did it through a /proc/container filesystem.
Which created the container object and then on fork/exec switched over.

How about an additional sys_exec_container( exec_args + "container_name").
This does all the work like exec, but creates new container
with name "..." and attaches task to new container.
If name exists, an error -EEXIST will be raised !
