How about that (modified 2.): All existing node objects also increase the
reference count of the doc object, and unref it on destruction. When doc's
refcount reaches zero, free the document. This way, doc is guaranteed to
be the last node alive, and when it dies, the libxml tree should go with
it.

Stupid me, could not think of that yesterday. This would also have been
easier in the wrapper.
