I think I did complain a little bit, but I'm not sure. I just had the
"feeling", that something started to go wrong. Only after people in this
list had discussions about the rationale of GPIO extensions, I
discovered the misconception, that I'm complaining about now.



Off topic: In Nut/OS history, this happened quite often. The system
timer code had been completely changed several times, until it reached
its current state. Many years(!) later, we discovered, that Nut/OS
context switching is extremely slow, compared to other OSes. Someone
(was it Nathan?) posted, that this is caused by the last changes in
timer processing. Note the present tense. It was never corrected,
because the following discussion never came to any result.
