   And I would not worry about multiprocessing queue problems in this case. In 
this case we have simple Producer -> Consumer case and we use it in the 
simplest possible way -> put() in producer and get() in consumer. The problems 
with multiprocessing queues that we experienced were related to rather complex 
pattern of using the queues where we had several queues synchronising 
back-forth and we were using length of the queue as indication of whether there 
is anything left for processing. I would however possibly think about 
increasing the maxsize of the Queue (will leave a comment there) to increase 
parallelism.
