Rails - Mar 2005 - Cleaning up has_and_belongs_to_many?

Does has_and_belongs_to_many know to delete an object when the last 
reference to it is removed?

In my case I have Receiver <<->> Message (with a join table of
course),
but have noticed that when the last receiver removes a message from the 
association the message still exists.

Before adding code to manage this situation I want to check to see if I 
am missing something?

I believe if you delete a Receiver or Message, the references are removed.

However, if you delete all the references, the objects are still there.
