+     * terminfo master file is large enough that some core-poor systems swap
+     * like crazy when you compile it this way...there have been reports of
+     * this process taking *three hours*, rather than the twenty seconds or
+     * less typical on my development box.
+     *
+     * So.  This hook *immediately* writes out the referenced entry if it
+     * has no use capabilities.  The compiler main loop refrains from
+     * adding the entry to the in-core list when this hook fires.  If some
+     * other entry later needs to reference an entry that got written
+     * immediately, that's OK; the resolution code will fetch it off disk
+     * when it can't find it in core.
+     *
+     * Name collisions will still be detected, just not as cleanly.  The
+     * write_entry() code complains before overwriting an entry that
+     * postdates the time of tic's first call to write_entry().  Thus
+     * it will complain about overwriting entries newly made during the
+     * tic run, but not about overwriting ones that predate it.
+     *
+     * The reason this is a hook, and not in line with the rest of the
+     * compiler code, is that the support for termcap fallback cannot assume
+     * it has anywhere to spool out these entries!
+     *
+     * The _nc_set_type() call here requires a compensating one in
+     * _nc_parse_entry().
+     *
+     * If you define HAVE_BIG_CORE, you'll disable this kluge.  This will
+     * make tic a bit faster (because the resolution code won't have to do
+     * disk I/O nearly as often).
