         BIND 8 is single threaded and this shuffling will indeed, by necessity,
  prevent it responding to queries and anything else until it's done with this. 10
  seconds does sound like a long time. Is your system heavily loaded, short of
  memory or perhaps is the disk badly fragmented?  This is not specific to NT
  as far as I know, just some things take longer on different O/S's.
