> With optimistic locking, we first check for an existing transaction, and if there isn't one, we implicitly start one. Before the method returns, if we started the tx ourselves, we make sure we commit it. 
> There is scope to 'replay' the tx a fixed number of times here if the commit fails.
> At the moment, if the developer explicitly starts a tx before any cache operations, the cache may throw a RollbackException if it is unable to commit. If the developer doesn't explicitly start a tx, the cache may fail silently if it is unable to commit, logging errors but not throwing any exceptions. So there is scope here for silent retries without changing usage semantics.
