+	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
