[Dxspider-support] IPV6 hangs

[Mike McCarthy, W1NR]

That timeout doesn't seem to have any effect on the problem I am seeing.
If I try to connect to a node via IPv6 and it does not answer, the
entire cluster comes to a stop for 2-3 minutes. And, if it is in
crontab, it does it over and over until the node is reachable once again.
