In what forum was that general agreement reached ? After 24 years on the market, VMS has rather extensive hooks for coding such schedulers, but it took many years to get to that point. There are many IO-related OS primitive measurements needed to achieve fairness. I presume you intended that the schedulers be adequate to meet needs rather than merely being flexible. I can make a scheduler much more flexible by adding an larger color palatte from which to enhance the logo it displays on a screen.
