Please could someone shed some light on what this bit of code is doing?

CRM/Core/Session.php line 126

      if ($config->userSystem->is_drupal && function_exists('drupal_session_start')) {
          // https://issues.civicrm.org/jira/browse/CRM-14356
          if (! (isset($GLOBALS['lazy_session']) && $GLOBALS['lazy_session'] == TRUE)) {
            drupal_session_start();
          }
          $_SESSION = array();
        }
        else {
          session_start();
        }
it appears to be checking if Drupal has acreated a lazy session.. if not, it creates one then wipes it?

This code is linked to an error where sessions for contribution and event bookings break if the session is lazy.  We still experience this issue with 4.5.5 and 4.6

@roxca,

The symptom of the issue I was having, that led to this code being inserted, is "After the page request is finished there will be two rows in the Drupal sessions table that share the same ssid (secure session id). Drupal assumes there is only one, which leads to all sorts of subtle, odd behaviours". In particular, folks would hit "Confirm" while registering for an event an be thrown back to an empty registration page, rather than progressing to the confirm page.

Do you have that symptom?
