Binding on addresses

[Chris Hills]

Hi

After changing configuration from "listen-on-v6 { any; };" to using 
specific addresses, I observed the following in the log after issuing 
`rndc reload` (times are CEST):-

29-Jul-2009 04:44:22.893 network: error: binding TCP socket: address in use
29-Jul-2009 04:44:22.893 network: error: binding TCP socket: address in use

After the reload, BIND no longer listened on tcp sockets, but udp 
sockets worked ok. After restarting named, it was listening on tcp 
sockets once more. Based on the log it looks like it is trying to bind 
to the address-specific tcp sockets before releasing tcp [::]:53.

BIND is 9.6.1-P1 on Linux x86.
