It uses a queue mechanism to get around JPA having problems when there are a 
lot of concurrent updates going on. 

Hibernate never had much of a problem no matter how hard we pushed it, but 
OpenJPA seems a bit more fragile, and so the queues buffer the update requests 
for shareddata and preferences to reduce concurrency.
