 I do not think this is the correct thing to do.  It is unacceptable to
 force a refresh of the window for every character as this may mean, in
 some very dumb terminal cases, a redraw of the screen.
 SUS v2 is not clear on the expected behaviour and I, personally, don't
 hold a certain other curses package as being authorative on curses
 A peek at the Open Solaris curses code shows they perform a fflush on
 the output file descriptor after the tput - I think that would be a
 better solution.
