>Summary: Persistent topic messages not removed from database

Initial Comment:
Persistent messages to administered topics are not being 
removed from the database when non-durable 
TopicSubscribers are used to consume them.

To reproduce
----------------
. create an empty database
. create a non-durable TopicSubscriber to administered
  topic "topic1"
. publish a persistent message to "topic1"
. after the subscriber has received and acknowledged the
  message, run the following query:
  select count(*) from messages;

  One row will be present in the database.

Workaround
----------------

To avoid this bug, use durable subscribers to consume 
persistent messages.

Fixed in CVS. Messages are now reference counted to ensure 
proper cleanup once the last consumer has processed them.
Fix will be available in the 0.7.7 release.
