 Since we probe the connection status, we'll keep a messenger as long
 as the connection is active, even if only on the incoming side.
 So we're being a bit nice to the other side. Anyway, incoming
 connections do not go away when the messenger does. There's a receive
 timeout for that.

  <p/>By analogy, a telephone number would be the destination address, and

  Each logical destination may be known by one or more destination
  addresses.

 <p/>By default the logical destination is the same as the destination.
