Synchronization in the sense of on-disk instance updates are all  
degree-2 transactional as I recall.  However the rub is the caching of  
class schema references in the slots of  persistent-metaclasses  
instances.  The transaction system doesn't help with side effects to  
non-DB objects.  Generally, schema updates are done by a single  
thread, but they may interfere with other threads that, for instance,  
are doing a lazy schema update on an access to a non-updated instance.
