I *think* the answer is somewhere between 400 and 600.  It has to do with
the number of responses that will fit into a UDP packet.

I *recall* that ntpd will not remember more than the last 600 (or so)

The previous ntpdc maintainer has gone and I would be happy to find somebody
to take over maintenance of ntpdc.

There has been some discussion that perhaps we could use TCP/123 for some of
these tasks, as we would not be limited by the UDP packet size then.
