Comment:

 > Way too much noise by default. Well over 24,000 log lines (even with
 incomplete run). Please by default just log to /dev/null.
 Done.  To make the output visible, set the environment variable
 B10_LOGGER_DESTINATION to stdout or stderr.  (I'll send an email round to
 bind10-dev to flag this and update the page in the wiki before I merge.)

 > I am not sure if this was introduced in this trac1024 branch, but I
 don't recall seeing it previously ...
 This problem was fixed in #1084.  Prior to making this change (to log to
 /dev/null by default), I merged master into the branch.  When you run the
 test, this should be fixed.
