Hi yet again, answering my own question 'Why doesn't 127.0.0.1 work in 
/etc/resolv.conf'

It doesn't work because the nameserver built into samba4 doesn't appear 
to listen on 127.0.0.1 !!!

netstat -lnptu (produces amongst a list of others)

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address

No mention at all of 127.0.0.1:53
