> Currently the store method in the CachingPersistenceManagerProxy performs an update on the PersistenceManager and then also updates the Cache.
> Since we are updating 2 resources, without any form of synchronisation its possible that the resources are out of sync.
> For example:
> Two threads A and B call configuration.update() on the same pid. The first threads calls store(), the PersistenceManager gets updated and then the second thread kicks in updates both PersistenceManager and the cache and finally the first thread updates the cache.
