Yes, at some point at least batch processing of simulations will be  
inefficient.
Every time you walk through the tree, the algorithm prefers to go the  
best path possible to gain more information. With each extra  
simulation in a batch there will be less and less useful information.  
Maybe there is a tradeoff and you can get away with small batches and  
gain something else. You have to test and see what happens.
