  Introduce reference transactions
  
  A transaction allows you to lock multiple references and set up changes
  for them before applying the changes all at once (or as close as the
  backend supports).
  
  This can be used for replication purposes, or for making sure some
  operations run when the reference is locked and thus cannot be changed.
