Just tried using wsoAsyncDnsLookup in a new component, and discovered a flaw in the implementation. Currently wsocket State is not changed when the DNS lookup starts, so it remains wsClosed, and applications are not aware it's happening, and it may take several seconds, or longer. So there is a risk of a second connect attempt. There is FInternalDnsActive flag which could be published and checked, or we could add a new State wsDnsLookup which would be easier to use since mostly we check for not wsClosed. But I'm always reluctant to change long defined stuff in case someone is checking for State >= wsClosed for instance, not a good design generally since it assumes the type has an order. So which change is safer?
