This will need some very careful design, because currently the data
structures we pass the terminal-specific backend is intimately tied up
to information known only to the display engine, like the faces
(identified just by their numbers), the font and font driver to use,
the window and the frame where to draw the glyphs, etc. Dividing this
between 2 threads, let alone processes, is not easy.
