Yes, that might work, too. On Unix and ncurses... But it involves some
relatively costly operations: Whenever I need to call something
(Scintilla message) that might result in a ncurses call I'd have to do:
 * copy the parameters
 * signal the UI thread; or interrupt the UI thread's event loop
 * wait on a condition variable.

I think that cbreak() and handling SIGINT is both more efficient and
elegant on this platform. On other Curses platforms I can still only
poll for the relevant key presses. Using multiple threads has no
benefit on these platforms (e.g. PDCurses on Windows console).
