Now we'll repeat all the setup that was done earlier.
We can execute this test with a single connection, because we're synthesizing the invalidation that is normally generated by the second connection. We need to create two revisions so that there is a non-current revision to load.

We still get a non-current version if the invalidation occurs while we are loading the current revision. Can that happen without ZEO?
