I guess I don't understand how a record would get whitelisted. The DUM
would get two records back from the SRV record, and try the first that
would be grey listed because of a timeout. It looks like a path is
whitelisted when there is a response that does not end in grey or black.

I guess I thought that because the 2nd record was never tried, you would
need to add them to the whitelist before hand so that on the next request
you would try the 2nd host first rather then the first timeout host.
