Wouldn't this be sensible to integrate into CFS _regardless_ of anything
else?
Especially with the alleged "pluggable" scheduler model, one of the things
lacking in any pluggability is the fact that the core thread data
structures are anythign but pluggable. This patch makes it no more so, but
at least it abstracts out the fields that are used by the scheduler, and
would seem to be a nice cleanup. No?
