 Description   

Mongos performs auto-split checking after batch writes have been applied. However, the auto-split logic currently only limits the maximum split points to 2. So if you have a 1MB chunkSize and jam the batch with 16MB worth of documents, the auto split logic will only split the chunks into 3, instead of 16.
