Will be used with the "generation id" infrastructure. When we're told that the commit failed because someone else made changes, we can use this to re-initialize the cache and then revalidate the transaction list (e.g. to detect that we now have to flush the user-defined chain 'foo' that we wanted to create, but was added just now by someone else).
