It would be, if it existed. Please read carefully what I wrote: "when
gotsig is forced to be 1 all the time", which is definitely not the case.

It would be, but you didn't do that, because you were not talking about
the actual code but about something else.
And please stop twisting around my words - I clearly said that this is
only true if gotsig were forced to be 1, which isn't the case. You now
make it seem as if I said there would always be such a delay.

Thsanks, will have a look - what you didn't mention, for example, is that you
fork, which is likely the crucial point.

You always assume something is useless if you don't understand
it: Don't. Try to understand it, don't make wrong assumptions.
