CFS maintains a time-ordered rbtree, where all runnable tasks are sorted by the -p->se.vruntime key (there is a subtraction using rq->cfs.min_vruntime to -account for possible wraparounds).

As the system progresses forwards, the executed tasks are put into the tree more and more to the right --- slowly but surely giving a chance for every task to become the "leftmost task" and thus get on the CPU within a deterministic
