I used strace on the postfix/master to find why it
was restarting. Something was sending it a SIGHUP.

I finally found:
/etc/default/bind9
which said:

OPTIONS="-u bind"
# Set RESOLVCONF=no to not run resolvconf
RESOLVCONF=yes

Resolvconf does this:

Overwrite (-a) or delete (-d) the nameserver information record for
network interface INTERFACE and run the update scripts in
/etc/resolvconf/update.d/ if the nameserver information has changed.

A named/BIND9 restart/stop/start did always invoke:
echo "nameserver 127.0.0.1" | /sbin/resolvconf -a lo.named
and this caused postfix to be signalled by resolvconf (after all, the
resolv.conf changed!)
