yes, I saw it too. curious to know what kind of command line argument

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.
