I am reasonably sure that the screen data structures get initialised
later, some of it may occur on the first call to refresh(), other bits
just after the screen is created.  If you can absolutely show that we
are referencing uninitialised data then sbutmit a PR and I will be happy
to have a look.

As a thought, I wonder if you are making things complicated for
yourself, you could split your program into two cooperating processes,
one that handles the async interactions with the hardware and the other
handles the UI.  That way you don't have to force the curses library
into a no-wait situation when it is not expecting it - curses does
handle not waiting in some situations but it is under the control of the
library.
