I realize that what I am trying to do is very easily accomplished with
instance of ntpd.  However, I assure you that the manner in which I am
trying to accomplish it is absolutely necessary for my particular

I found a definitive answer in the code.

ntp_io.c, line 1232

 * Check to see if we are going to use the interface
 * If we don't use it we mark it to drop any packet
 * received but we still must create the socket and
 * bind to it. This prevents other apps binding to it
 * and potentially causing problems with more than one
 * process fiddling with the clock

This explains why an instance was still receiving packets from an
that was not specified with '-I'.

Thank you very much for the help.
