Interesting. Do you know if multiprocessing forks the Python interpreter? Have you looked at what happens to the clinet's background threads? I've had multiple problems with multiprocessing that refused to work in the presence of non-picklable objects even if they were never passed between processes. Mutli-threading deadlocks with a lot of C extensions, I've seen numpy break if it was used on unrelated arrays in different threads.
