+Each successful call to \fBsetupterm\fP allocates memory to hold the terminal

+Before ncurses 6.3, those were shared by all screens.
+With ncurses 6.3, those are allocated per screen.
+See \fBterminfo\fP(\*n) for details.
+.bP
+to improve performance, ncurses 6.3 caches the result of analyzing terminfo
+strings for their parameter types.
+That is stored as a binary tree referenced from the \fBTERMINAL\fP structure.

+The higher-level \fBinitscr\fP and \fBnewterm\fP functions use \fBsetupterm\fP.
