+ * 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).
