Yeah, I know what it is, I need a work around for it :)

More like 15:

  # time host foo
  Nameserver not responding
  foo.foo.com A record not found, try again

  real    0m14.996s
  user    0m0.000s
  sys     0m0.000s

Probably not.  This is for an embedded system, for which the desire is
a little complexity as possible.  Configuring a caching name server
would a significant layer of complexity for which our support people
are not qualified to deal with.  Additionally, the configuration of
the caching server would be a royal pain to build into our
installation process.
