This is unbelievable...

At least the connection that made the modification should
see the changes (it itself has made).

Indeed, all connections on the ZEO client that made the modifications
should see them. This is due to the "callback" in
"ZODB.Connection.Connection.tpc_finish".
This callback is called in the storage's "tpc_finish"
and invalidates (flushes from ZODB cache) all objects
modified in this local transaction.
