+       Any implementation of curses must not free the memory associated with
+       a screen, since (even after calling endwin()), it must be available
+       for use in the next call to refresh().  There are also chunks of
+       memory held for performance reasons.  That makes it hard to analyze
+       curses applications for memory leaks.  To work around this, build
+       a debugging version of the ncurses library which frees those chunks
+       which it can, and provides the _nc_free_and_exit() function to free
+       the remainder on exit.  The ncurses utility and test programs use this
+       feature, e.g., via the ExitProgram() macro.
