Comment:

 I've put in a few logging statements, but in a module such as this, buried
 deep in the internals of the resolver, it's difficult to add anything
 other than debug statements.

 Three debug levels have been used: one for tracing "normal" operation
 (requests from the rest of the resolver), one to report the results of
 those requests, and one to report RTT results.  Only a few messages have
 been used - as we get more experience, we may want to add more.
