Right, the buffering is not on the application side, it's on the system
side, so you need to change the terminal mode. So... there are already
four different Ncurses libaries available. It should be trivial to make
a soft port that calls getch.
If you can wait a day, I'll be releasing a new version of mine
(current is at http://www.pyro.net/~crayc/guile-ncurses.tar.gz)
tomorrow that will work with 1.6.
