	yes, I saw it too.  curious to know what kind of command line argument
	you were using with mdnsd.  probably with -N (lookup by ping6)?

	hmm.  i'm preferring not to change timings for calling res_init(),
	as your change would call stat(2) every time we call gethostby*...
	maybe having some timer/time offset between stat(2) calls, so that
	we won't check it every time?

	i guess it nicer if we can add "destination port number" argument,
	so that we can talk with multiple local instances of nameserver, like:
		nameserver 0.0.0.0 10053	# mdnsd
		nameserver 0.0.0.0 53		# normal named
	it would eliminate the need for dynamic res_init().  not sure if
	it is workable or not.
