[SVN commits to the Digium repositories]

New Revision: 102856

URL: http://svn.digium.com/view/asterisk?view=rev&rev=102856
Log:
Another checkpoint. Found a set of places where the results of a find_user or find_peer call were not unref'd when the pointers went out of scope. Now, all the peers and users seem to be destroyed properly, but I found another dialog that isn't being freed... sigh.
