Adapter statistics on the adapter page seem to only update once an adapter operation (eg. full or delta import) has completed, and not as processing begins.
This cache is only cleared on Completed events for the Adapter jobs. This isn't a problem for smaller operations like Add Entity, Update Entity etc, and hasn't been a problem for Adapter import all due to the speed of LDIF generation in version 4.0.
All this will require is another notification factory to clear the cache on the AdapterEngine::ReflectPage method.
