Description

As mentioned in this 

https://github.com/apache/lucene-solr/pull/513#discussion_r399131681

the method clearDeletedDocIds in BufferedUpdates.java has a bug, it can't reset bytesUsed correctly

void clearDeletedDocIds() {
  deleteDocIDs.clear();
  bytesUsed.addAndGet(-deleteDocIDs.size() * BufferedUpdates.BYTES_PER_DEL_DOCID);
}
