7da88b772f Scheduler: setup to verify the work-Function 
...first steps to get anything to run with the Scheduler constructed thus far
...can now
 - enqueue
 - getWork -> invoke

a180d38ed9 Scheduler: integrate capacity handling with work-Function 
...this integration becomes more and more challenging
...the high degree of inter-correlation between the scheduler components is concerning

1d5b8c3e9c Scheduler: implement and verify random reshuffling of capacity 
...using the current time itself as source for randomisation;
the test indicates this yields a smooth and even distribution.

3eaf623e98 Scheduler: develop scheme for capacity redirection 
...to make that abundantly clear: we do not aim at precision timing,
rather the goal is to redistribute capacity currently not usable...

Basically we're telling the worker "nothing to do right now, sorry,
but check back in <timespan> because I may need you then"

08c13ed6fe Scheduler: consider wiring of Load-Controller 
...and general questions of component design and coupling.
Decided to go for explicit configuration points by functor.

69fb77246e Scheduler: implement capacity redistribution scheme 
wow... that was conceptually challenging, yet dead easy to implement

6ccb6540e6 Scheduler: implement the tended-next mark 
...as KISS solution to put aside the next free capacity
whenever a new time point appears at scheduler head

84ca2460c1 Scheduler: fundamentals of capacity classification 
Workers asking for the next task are classified as belonging
to some fraction of the free capacity, based on the distance
to the closest next Activity known to the scheduler

e5638119f5 Scheduler: devise scheme for load control 
- organise by principles rather than implementing a mechanism
- keep the first version simple yet flexible
- conduct empiric research under synthetic load

Basic scheme:
- tend for next
- classify free capacity
- scattered targeted wait
