We seem to be going around in circles, or talking on different
frequencies, or something.

Lets try to go back to the basics:

My apt-sources contains:
deb http://snoopy.apana.org.au:8081/debian/ woody main non-free contrib
deb http://snoopy.apana.org.au:8081/debian/ unstable main non-free contrib
deb http://snoopy.apana.org.au/~ftp/debian woody main

My apt/preferences file is setup so that the 2nd line has a priority -1,
so it should effectively be ignored, right?

Also, the version in woody is old, so that line should be ignored
too, right?

That leaves one line left to be processed, the last one.

I then run an "apt-get update" operation. This will download this
entry from the Packages file:

Package: kerberos4kth1
Version: 1.1-11-2
Priority: optional
Section: net
Maintainer: Mikael Andersson <mikan@debian.org>
Architecture: all
Filename: ./pool/krb4/kerberos4kth1_1.1-11-2_all.deb
Size: 57786
MD5sum: 330d49310a3264f037875e06a1328458
Description: Dummy library package for Kerberos4 From KTH.
 This is a dummy package. It should be safe to remove it.
installed-size: 76
source: krb4

This MD5sum matches that of the file on the server, exactly:

[518] [snoopy:unstable:bam] /home/ftp/pub/debian >md5sum ./pool/krb4/kerberos4kth1_1.1-11-2_all.deb
330d49310a3264f037875e06a1328458 ./pool/krb4/kerberos4kth1_1.1-11-2_all.deb

The MD5sum is also exactly the same on the file downloaded on
the client.

I then do "apt-get upgrade" two times in a row, and it upgrades
the same set of packages twice.

Why?
