I don't understand your point. Quoting from Wikipedia
(https://en.wikipedia.org/wiki/Apollo_Guidance_Computer): "Luckily for
Apollo 11, the AGC software had been designed with priority scheduling.
Just as it had been designed to do, the software automatically
recovered, deleting lower priority tasks including the 1668 display
task, to complete its critical guidance and control tasks."

Robust against what? Requirements changes? Programming errors? Temporary
overloads? I don't see it, whatever robustness measure you use.

And I don't understand why you don't. I don't think you have shown any
reasonable grounds for this distrust.

It is several things:
- extra work to design the scrubber SW, since it now depends on the 2 ms
requirement
- extra work to verify that the design is correct and the 2 ms
requirement is correctly implemented in the scrubber SW
- extra maintenance work if either the 2 ms period changes, or the
scrubbing requirements change
- in general, it adds an unnecessary dependency between the 2 ms task
and the scrubbing task, both at design time and at run-time, and so
violates design modularity.
If the whole design would be based on this principle, the same extra
stuff would enter the other 18 or so tasks, too. Moreover, some part of
the code would still have to decide that the 2 ms task should be run
more often than other tasks, and that application code would in effect
either reimplement priority-based scheduling, or EDF scheduling, or some
similar system, or would be based on a statically predetermined
"minor/major cycle" type of scheduler, which can be severe burden on SW
maintenance.

My current memory scubber object understands its CPU budget: it is
allowed (and even required) to use all the CPU time available at its
priority level.
What I don't want to do is to force the scrubber task to understand the
CPU budgets of the *other*, higher-priority tasks.
And the scrubber task is beatifully simple, just a couple of nested
loops, the outermost being eternal. Completely robust against any
conceivable change in any other part of the application, and against any
overload.
But I admit that the scrubber task is a special case. At higher
priorities, to be robust against overloads the tasks may have to
implement load-shedding or load-refusing logic such as limiting the rate
at which the task is triggered by sporadic inputs. However, IMO even
such things are easier in a preemptive system.
Can you explain how you would design a memory scrubber object, in a
non-preemptive system, to support not only the 2 ms task, but tasks at 1
Hz, 10 Hz, and five (say) sporadic, I/O-triggered tasks at rates of up
to around 50 Hz?
