   You must have an old man page (but I remember SIGIOT from somewhere).
   On a Sun here and now (SunOS 4.0.3) it's:

	SIGHUP     - reload
	SIGINT     - dump to /var/tmp/named_dump.db
	SIGUSR1    - increment debug level (output to /var/tmp/named.run
	SIGUSR2    - turn debugging off

No, I believe it's Sun that's running the old version of Bind.  SIGINT
dumps the named cache to named_dump.db.  On newer versions of BIND,
SIGIOT dumps statistics (number of input packets, number of output
packets, number of queries, number of queries broken down by type, etc.)
to /usr/tmp/named.stats.
