What does "poll invalidation" mean?

  The RelStorage maintains a sequence of (object) invalidations ordered
  by "transaction-id" and the client can ask "give me all invalidations
  above this given transaction id"? It does so at the start of each
  transaction?

In this case, how does the storage know when it can forget
invalidations?
