> 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.
