    // In Drupal's distributed database structure, new data is written to the
    // master and then propagated to the slave servers.  This means there is a
    // lag between when data is written to the master and when it is available on
    // the slave. At these times, we will want to avoid using a slave server
    // temporarily. For example, if a user posts a new node then we want to
    // disable the slave server for that user temporarily to allow the slave
    // server to catch up. That way, that user will see their changes immediately
    // while for other users we still get the benefits of having a slave server,
    // just with slightly stale data.  Code that wants to disable the slave
    // server should use the db_ignore_slave() function to set
    // $_SESSION['ignore_slave_server'] to the timestamp after which the slave
    // can be re-enabled.
