I fear the ZODB is not made for this use case.

Synchronization is in the form of invalidation messages
deeply embedded into the ZODB.
You may simply delay the invalidation messages and
thereby delay synchronization. However, you will problably
suffer from the lack of prefetching support and the need
to synchronize any modification immediately with the ZODB.
