It doesn't. Absent instantaneous network transmission, that's
impossible.  What it does is makes sure a client sees all changes made
prior to the start of a transaction. It does this by sending a
do-nothing ping to the server waiting for a response. This assures
that it receives and processes any in-flight invalidations prior to
starting a new transaction.

With ZEO 5, add:

  server-sync true

to your clientstorage (rather than zeoclient) configuration. See:
