Description zhang jianfang 2010-08-03 06:08:39 UTC 
Each time loading an ODF document, it created an UNO XML DOM tree and a
corresponding libxml DOM tree. The root node of UNO XML DOM tree is CDocument
node. In DOM::CDocument::~CDocument(), all uno dom nodes and libxml dom nodes
will be released. 

The problem is the created CDocument object is never released, because there are
cyclic reference between CDocument and all it's CNode objects.
CDocument.m_aNodeRefList keeps reference to all CNodes it creates while each
CNode.m_rDocument keep reference back to CDocument object.

The problem can be observed if you simply open/close any ODF documents.
