Class PersistentQueue

object --+
         |
        PersistentQueue

Keeps a list of abstract items and serializes it to the disk.

It has 2 layers of queue, normally an in-memory queue and an on-disk queue. When the number of items in the primary queue gets too large, the new items are automatically saved to the secondary queue. The older items are kept in the primary queue.
