Comment (by Dhalgren):

 One obvious difference is that `named` times-out requests in ten seconds
 and does not fall-back to TCP (with DNSSEC disabled), at least when
 querying via `dig`.

 `Unbound` tries for 120 seconds, falling back to TCP.  Researched
 `unbound` time-outs and did not find a way to modify the behavior.
