Implemented in svn trunk that if all the servers are blacklisted, then
99% of queries are stopped.  So, very busy domains get polled more
often, without being a hindrance in traffic volume. Quiet domains get
the normal 15 minute timeout.

I think this might have changed Dmitriys situation so that the forwarder
is probed quickly after the connection resumes.

Best regards,
