from doc/misc/migration:

   1.1. Unimplemented Options and Changed Defaults

   BIND 9.0.0 supports most, but not all but not of the named.conf
   options of BIND 8.  Unimplemented options include those for selective
   (per-domain) forwarding, sortlists, statistics, and process limits;
   for a complete list, see doc/misc/options.  We plan to implement most
   of these in in BIND 9.1.

   If your named.conf file uses an unimplemented option, named will log a
   warning message.  A message is also logged about each option whose
   default has changed unless the option is set explicitly in named.conf.

   In particular, if you see a warning message about the default for the
   "auth-nxdomain" option having changed, you can suppress it by adding
   one of the following lines to the named.conf options { } block:

      auth-nxdomain no;    # conform to RFC1035
      auth-nxdomain yes;   # do what BIND 8 did by default

oh, and the documentation isn't finished yet.

i never looked.  then again, i fully expect things that do all the
work that bind does to be complex and not understandable at a glance.
i have a rule of thumb that i know how to operate the tools i use,
even if i don't understand exactly how they do it.

isc betas are usually quite stable, and the 8.2.3 code is derived from
the 8.2.2 code which also worked fine for me while i was running it.

i'm not debating the use of threads in userland or kernelland...but we
don't have them, so threaded apps are very likely not gonna get

the point was that the base system doesn't depend on something not
