 There's code comment mentioning a seeming function called
 `setUnitTestRootLoggerCharacteristics`:
 {{{
     // Now set reset the output destination of the root logger, overriding
     // the default severity, debug level and destination with those
 specified
     // in the environment variables.  (The two-step approach is used as
 the
     // setUnitTestRootLoggerCharacteristics() function is used in several
     // places in the BIND 10 tests, and it avoid duplicating code.)
 }}}

 But it doesn't even seem to be declared anywhere.  Maybe it's some
 leftover?  If so, the comment should be updated.

 I guess it's a good topic for hardening.
