from the docs about "switch-page":
"Emitted when the user or a function changes the current page"
a.) "switch-page" maybe isnt exactly where all that logic belongs ?
b.) maybe your code actually _knows_ that it is in the process of manually
setting the page of the notebook and should just behave accordingly ?

Signals are part of regular program flow, all (or almost all) signals
can be triggered programatically - some are triggered by the object code
that that recieved an event - some signals are triggered by your code
since you called an api from a callback in another signal, this can
and will get very recursive under normal circumstances.
On the other hand, there is a slew of signals on GtkWidgetClass that
are infact "event" aliases delivered from gdk, they all bear the "-event"
suffix and its worth knowing the difference between the two.
