Doesn't matter... it's an implementation detail. Solr used to buffer deletes, and if it crashed at the right time one could get duplicates. Now, Lucene does the buffering of deletes (internally lucene does the adds first and buffers the deletes until a segment flush) and it should be impossible to see more than one "1" or no "1" at all. -Yonik
