Several Debian based distributions were recently found to have omitted a kernel configuration option that had the effect of rendering /proc/#/stat and /proc/#/wchan useless for providing any 'sleeping in function' info. That problem also prompted a reevaluation of the whole approach to wchan matters which had grown increasingly complex as our library evolved over the last 13 years. The net result was a decision to rely on /proc/#/wchan which arrived along with the 2.5 kernel. This then let us vastly simplify the internal code plus the external interface which will benefit both the top and ps pgms.
