I was trying to check on error logs after a brief Phabricator outage earlier today and noticed, again, that there's a ton of noise in /var/log/apache2/phabricator_error.log.

On closer inspection, I located a debug phlog() that seemed safe to get rid of and
was generating most of the logspam. I'd like to keep an eye for a few days and see what
else could easily be cleaned up here.
