btw "fair" is an entirely subjective and unproductive way to describe a system. There's simply properties and priorities. Many of us have learned fair to mean a great variance of things. From per capita equal load, to you get what you pay for, to anything goes just don't hurt anyone. In families we might see this as each child gets the same number of cookies. In capitalism fair is what you negotiate and agree to. The point isn't what is or isn't fair, but that there is no universal "fair".
Should a user be able to jump the queue? What if they're your number one driver of revenue? Or they have a time-sensitive function w/ a deadline? Or if they've produced no load on the system in the past $TIME_UNIT. All of these are not fair, just properties to be designed into a product.
