How is access synchronisation to such a structure handled in Zope? What
happens automatically? What do I have to do on my own?

First come, first serves. There is no fancy synchronization. If two threads are trying to modify the same object then one thread will receive a WriteConflict error. It is up to the app to deal with these kind of errors. In the Zope 2 world Zope tries to re-do the current transaction for up to three times before the ConflictError is passed up to the application.
