That is unfortunately true.

I dislike that variant very much. Whenever your app creates a thread which 
calls into libxml, libxml will create an additional one, a courtesy of the 
braindamaged Windows thread API.

I would personally rather disable threads altogether, but if the public 
wishes for native threads, native threads they will get :-)
