The hints file is used by BIND only at startup time to ask one of
the real root servers for the current list of root servers.  Once
BIND has gotten an answer from a real root server it throws away
the root.hints info and uses the list the root server returned.

So the worst case I can see for lookup delays is that first query
to find root servers when BIND starts might need to be repeated,
if you got the 1 in 13 which is old and if that 1 did not respond.
