I honestly do not understand what I have written which gives you that idé.

If I can get a value from the kernel instead of from the process,
I'd take the kernel value.
Why do a process have to query the kernel to get a value and then
sending it to a monitor over a communication link; why don't the
monitor query the kernel itself, saving one step.

It would help my understanding if you simply answered my question.

This is not as a suitable metaphor as you think it is.
