+SunOS 4.1.X curses is broken.  It occasionally repaints the wrong thing
+on the screen, and nobody has been able to figure out a workaround other
+than to rewrite curscr every time stdscr is modified.  This, obviously,
+trashes performance.  A test program is attached.

+ * The broken behavior can be seen in that the line is first displayed,
