  // Ignore slave database servers for this request.
  //
  // In Backdrop'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.
