an will not be saved, we will have to clear

So there should be multiple subsections for every possible field?
E.g. timers are saved only if they are pending, thr_ipending is saved
only when it is nonzero, and so on. Do you mean that?

Hmm, probably not. The bug would not be other timers accessing the
