You are running the "asyncore" main loop in a separated thread?

If not, a client storage processes invalidation messages only
when used. Often the necessary objects are already in the ZODB cache
and the storage is not used.

Also note that you will see changes only at transaction boundaries.
Inside a transaction, you will never see any changes.

The ZEO connection was closed.
