Mis-assigning priorities is IMO the same kind of programming error as 
mis-defining the termination condition of a loop. But it would be 
nonsensical to say that it is bad if an application depends on the 
termination condition of a loop.

I believe I do understand your concern, that changing the priorities 
should not change the "result" of the program, for example because 
priorities have been used to control the sharing of data between tasks, 
such that changing the priorities causes (different) data-access races 
and thus changes the data-flow in the computation.

Mutual exclusion and race-prevention *can* be implemented correctly by 
priorities (for example using the Immediate Priority Ceiling Inheritance 
protocol, as in my application), but of course it can also be done 
incorrectly.

However, in a real-time application the behaviour always depends on the 
timing of the SW actions, even if there are no data races in the SW. For 
example, if the SW is supposed to sample an ADC at 100 Hz, but the new 
priorities mean that it is sampled only at 50 Hz, or with a large 
jitter, inevitably the results will be different, and perhaps useless. 
(You can say that in this case there is a data-race between the SW and 
the HW, and I would agree, but that is typical for real-time systems.)

I have something like 20 tasks, at multiple priorities and with some 
complex interactions. I use priorities to gain determinism, not to lose it.

The kernel in this application (the AdaCore RTS for the LEON2 processor) 
is tickless. The clock and timer resolution is sub-microsecond. Task 
switch times are about 50 us on this 86 MHz processor.

I totally disagree. A non-preemptive system would force me to insert a 
large number of "yield" calls in all tasks, carefully placed so that the 
execution time between yields never exceeds the maximum latency I allow 
for the 2 ms task. Yuck, yuck, triple yuck.

> Hopefully, you have a good handle on the jitter for the 2ms task.

I believe I do. With the preemptive and tickless kernel, it is limited 
by the maximum duration of actions at higher priorities. As this task is 
the highest-priority task, only interrupt handling and other 
interrupt-level operations (start/stop I/O) can cause jitter.

The ever-ready background memory-scrubbing task plays that role in my 
application; the actual scrubbing rate is an estimate of the CPU load 
posed by the other, higher-priority tasks. This is a very common design 
in this domain (satellite on-board SW).

If I want to have more detailed measurements, I can use the kernel's 
task-specific and interrupt-specific CPU-time accounting.
