      When inserting a very long list of DBObjects, a bufferoverflow exception is thrown:

      Exception in thread "main" java.lang.IllegalArgumentException: tried to save too large of an object.  max size : 2098176
	at com.mongodb.ByteEncoder.putObject(ByteEncoder.java:175)
	at com.mongodb.DBApiLayer$MyCollection.insert(DBApiLayer.java:203)
	at com.mongodb.DBApiLayer$MyCollection.insert(DBApiLayer.java:162)
	at tv.miniweb.mediasearch.indexer.Indexer.Index(Indexer.java:54)
	at tv.miniweb.mediasearch.indexer.IndexerLauncher.main(IndexerLauncher.java:53)

      This is because a single ByteEncoder is used for the entire .insert request, which is IMO not optimal behaviour in this case. I have pushed a git changeset with a patch and unit tests that fix this.
