no problem even under the current model, and it has happened before. We
made the scheduler itself easily 'rip-out-able' in 2.6 by decreasing the
junction points between the scheduler and the rest of the system. Also,
the current scheduler is no way cast into stone, we could easily end up
having a different interactivity code within the scheduler, as a result
of the various 'get rid of the two arrays' efforts currently underway.

Do you honestly think with the current "2.6 forever" development process that this is likely, even possible any more?

Given that fact, it means the current scheduler policy mechanism is effectively set in stone. Do you think we can polish the current scheduler enough to be, if not perfect, good enough for _every_ situation?

Noone said that if we have a plugsched infrastructure that we should instantly accept any scheduler.
