PANDA_STATISTICS_LOG  A path.  Points to a file on disk where you'd like the panda daemon to occasionally write statistics about its performance.  Mostly for debugging.  Defaults to '/tmp/pandaStatisticsLog'.
 
 PANDA_JOB_ATTRIBUTES A space-separated list.  If you only want to send a subset of job attributes, list those attributes in this configuration macro.  No default, but if the macro is unset or empty, the daemon sends all attributes.

+If you set PANDA_QUEUE_GRACE to one more than PANDA_UPDATE_TIMEOUT, you should only lose that single timed-out connection's updates.
+
+Updates happen no more than once a second, although on an idle schedd, they may happen less often.
+
+By "updates", the previous sentence means "one ADD command, one UPDATE command, and one REMOVE command" (in that order).  This is probably true elsewhere on this page.
