We want to throw QueueCacheMissException if we cannot guarantee that we didn't miss any event. QueueCacheMissException should be handled by the application code, and should be read as "we may have missed some events for this stream".

The lastPurgedToken dictionnary might not contains all the purged token (only recent streams purged by this streaming agent).

from orleans.
