Hi Craig, Et al,

I've got some local hacks that yield correct ps & top results under lxc 
and docker containers and set the stage for adjusting uptime (when 
necessary).  However, there's no guarantee my assumptions extend to any 
other types of containers.

What that effort suggested is such code almost certainly doesn't belong 
in our library.  I agree with Krzysztof that containers are a problem 
that probably should be addressed in the kernel.

The attached patch corrects an existing oops discovered along the way. 
Thanks in advance for the push.

Regards,

Jim
