It struck me that we could also consider redoing the threaded solution
somewhat more and perhaps have a thread-pool with N threads for name resolves
and they could stay alive during the multi handle's entire life time so that
we don't have to start/kill threads to the extent we do now and we could get
away with less threads than number of simultaneous easy handles.
