      Description

      Was reviewing messages backup, in order to fix MDL-9089, when I've detected that code performs this:

      $unreads = get_records ('message');
      $reads = get_records ('message_read');
      $contacts= get_records ('message_contacts');

      ... causing big memory usage in sites with thousands of messages. Going to switch to recordsets instead.

      Ciao
