I wonder what you try to gain by using multiple threads with what is essentially an IO-bound operation.

I wouldn't try to do IO on the same channel with more than one thread. If you want to create XML fragments and output them in parallel, I would create the fragments in separate threads and send them to one output thread via Thread::Queue.
