I should mention that there is /still/ some overhead involved when you mix
documents from different threads here (as everywhere in lxml), including
the stylesheet itself. However, as this also runs with the GIL released,
your gain on multi-processor machines will still be higher than the
overhead. YMMV, as usual, so profiling is always a good idea. :)
