This is just another (obvious) degree of freedom, which could be
interesting to explore in stress testing, while probably not of much
relevance in practice (if a job is expected to become runable earlier,
in can as well be just scheduled earlier).
Some experimentation shows that the timing measurements exhibit more
fluctuations, but also slightly better times when pressure is low, which
is pretty much what I'd expect. When raising pressure, the average
times converge towards the same time range as observed with time bound
propagation.
Note that enabling this variation requires to wire a boolean switch
over various layers of abstraction; arguably this is an unnecessary
complexity and could be retracted once the »experimentation phase«
is over.
This completes the preparation of a Scheduler Stress-Test setup.
