Looking for prioritized curses

[William Lewis]

   I'm looking for a set of routines that's vaguely like curses, except
with a bit of handling for low baud rates (2400, 1200, 300...) Specifically,
what I want is a refresh() function that will send output in the "background"
(spawn another task for buffer-flushing) and if another refresh() is 
performed before the previous one has squeezed through the tty, will
dump the previous output and start again (but keeping track of the
modifications that have already been sent). Ideally, it would also let
me prioritize areas on the screen so that when a new refresh() occurred,
it would redraw high priority areas first and work its way down.
  An example: Say I have a program that puts a bunch of stuff up in the
middle of the screen, then calls refresh(). So curses immediately
starts redrawing the center of the screen. Now, the application makes
some global change to the screen-center (pages the window, or something).
The program I'm looking for would stop terminal output immediately,
and start on the redraw again with the new info in mind. Curses as it
already exists would first completely finish the first redraw, then
immediately overwrite it with the second (except not so immediately
at 1200 baud =8( )
  Does anyone know of anything that matches this description? Hopefully
it would be vaguely portable, but I'm looking for something that would
run under 4.3BSD or Dynix.
