> GrammarResolver.cpp allocates XMLSchemaDescription out of wrong pool
> This causes a memory leak and thread safety issues when sharing
> an unsynchronized grammar pool across multiple threads.  I included diffs
> that affect my application. It would be good if somebody could check all uses of
> fGrammarPoolMemoryManager to verify the immutability of cached grammars
> and thread safety for the GrammarPool.  When not parsing grammars, the
> pool should not change.  I think fGrammarPool->createSchemaDescription may
> be generally dangerous.
> <             XMLSchemaDescription* gramDesc = new (fMemoryManager) XMLSchemaDescriptionImpl(namespaceKey, fMemoryManager); 
> ---
> >             XMLSchemaDescription* gramDesc = fGrammarPool->createSchemaDescription(namespaceKey);
