To better cope with round robin pooled A records like keys.gnupg.net we need to keep some information on unresponsive hosts etc. What we do now is to resolve the hostnames, remember them and select a random one. If a host is dead it will be marked and a different one selected. This is intended to solve the problem of long timeouts due to unresponsive hosts. The code is not yet finished but selection works.
