Mattias Falk a59cfcfd08 Avoid multiple dns lookups for the same query ...

If two or more rapid dns requests for the same server are done
from different threads it turns into separate dns reques, if
the response of the request isn't found in the cache.

This patch avoid multiple request for the same server by
letting subsequents request wait until the first request
has finished.
