Description: Ubuntu 10.04.3 LTS, 10.10. 11.04. 11.10, 12.04 pre-release
Release: 10.04, 10.10, 11.04, 11.10, 12.04 pre-release
2.6.37-02063706-generic, and all kernels since, including the current RC at kernel.org
load average doesn't seem to be registering for sleeping processes, as demoed here: http://www.youtube.com/watch?v=KjSZ-D0XBBQ
