There are freethreaded classes as well.

I think your best bet at the moment is to load whole document at once
from stream, on endDocument. Right way would probably be similar to how
libxml2 does it - using SAX callbacks to construct DOM tree, and then
using SAX reader when loading from stream, or writer calling them.
