*sigh*  I am fully competent at maintaining my own local changes.  The point
was to share this so that other people with similar workloads could make use 
of it.  Also, a custom CC algo is not the right approach as we would want this
change regardless of the CC algo used for handling non-idle periods (so that
this is an orthogonal knob).  Linux also makes this an orthogonal knob rather 
than requiring a separate CC algo.
