My take on change is that we should be doing as good a job as we can
with the scheduler we have so users get whatever we're able to deliver
at the current time.  Having to change in kernel code shouldn't be that
big a deal, especially with something like this where the scheduler is
free to ignore what it's told without churning the interface.
