Description

We've been bitten several times in the field now by various icmp issues where the ping is actually working just fine, but reverse DNS is ongoing and therefore we don't end up getting an answer for quite some time. Combined with 6210, this leads to some particularly nasty failures and confusion. Instead, if we're in this state where we've been blocked on name lookup for so long, then we go ahead and just warn to the user once per minute.
