      Description

      We're getting lots of lock timeout exceptions on moodle.org cron:

      $ grep locktimeout moodle_cron.log | wc -l
      194
      

      It looks like its just the general '1 minute' lock -

       grep -A3 locktimeout moodle_cron.log
      [2014-10-28 06:59:13.034470340+08:00] Error code: locktimeout

      So perhaps this shouldn't be an exception?
