Yes, basically that works fine.

Problem is the idle function added with

https://developer.gnome.org/glib/stable/glib-The-Main-Event-Loop.html#g-idle-add

I have the strong feeling, that the provided function is not running
silently in the background, but it is just called at some point and
then blocks user input until the function terminates. At least, when
that function is added with g-idle-add on GtkTextBuffer changed signal
and that functions does only a delay of 2000 ms, then for that time
user input into text buffer is blocked.

That was not what I expected. And it is bad, user input becomes a bit
sluggish.
