unbound listening sporadically on 0.0.0.0 high ports when configured for 127.0.0.1 ?

[Paul Wouters]

See https://bugzilla.redhat.com/show_bug.cgi?id=1342105

 	from time to time "netstat -l" shows unbound listening on some high-ports not
 	bound to 127.0.0.1 - that makes no sense when the service is configured for
 	127.0.0.1 only as a local resolver on a inbound mailfilter

 	udp        0      0 0.0.0.0:42663           0.0.0.0:*
 	563/unbound
 	udp        0      0 127.0.0.1:53            0.0.0.0:*
 	563/unbound
 	udp        0      0 0.0.0.0:12387           0.0.0.0:*
 	563/unbound

 	unbound.conf

 	 interface-automatic: no
