Perhaps, but given the current mechanism it does influence how often
that node is contacted - a node will be contacted roughly in proportion
to the number of references it has in the datastore, which will create a
positive feedback loop and make the problem even worse.

In a healthy network, the number of times the same DataSource is
returned for different keys should be so small as to make the problem of
throwing away data negligable.

Having said that, and after some IRC discussion, I have realised that
another solution which should fix the problem as a side-effect is to
periodically split DataRequests and take the DataSource in the first to
return.  The main reason for doing this is to make the network optimise
to the physical Internet by creating a bias for faster routes.
