Correct, yes. The context is the same we do CC conversion with and there it
works perfectly fine. We also hold a lock to make sure that the context isn't
used by more than one theread at the same time.

Well, using the auxiliary context migth work around the problem but won't
really solve it. Anyway a patch going this approach is attached, please test.
